LVDS .MultiplexingA laptop system can have two LVDS transmitter sources: embedded chip and external video chip. Embedded LVDS is used in the battery mode for power saving, while the second external video is higher performing and is used in AC power mode.
The standard LCD panel module uses LVDS signals by four-pair, five-pairs and 10-pairs, depending on the defined standard panel size.
TS3DV416 is a four-pair and TS3DV520E is a five-pair. Both can be used in LVDS, TMDS, DVI and HDMI. VIO ranges from 0 V to 5 V, with a single supply of 3.3 V.
The internal charge pump enables the I/O signal rail to rail up to 5 V, exceeding the supply voltage.

USB .2 .0 .SwitchToday, laptop computer USB ports are utilized not only for data transmission but also as isolation for host charger settings.
To enable laptop computers to charge portable equipment in power-down mode or shut-down modes, it requires a USB 2.0 switch MUX to connect the circuit of the host charger, which needs D+ and D– by 100-K resistor short. In iPod charger mode it uses pull-up and pull-down resistors.
The CBT3125C is a quad SPST and can be applied to both charging-mode connections.
The SN74CB3Q3253 is an alternative device for this application, featuring dual SP4T with 500-MHz bandwidth to meet USB 2.0 (480 Mbps with 240-MHz bandwidth minimum).

HD .Audio .Bus .TranslatorHigh Definition (HD) audio is quickly becoming the proven method for audio signals, allowing for much higher quality play back of audio signals compared to previously integrated audio codecs. When the HD audio controller sends signals out to either the audio codec or the modem codec, and voltage data line discontinuity occurs, where one accepts 3.3 V and the other 1.5 V. This is when our audio bus translators come in, allowing for seamless voltage level translation between the two mismatched voltages.
The HD_audio interface can be configured to use either 3.3 V or 1.5 V.
The TXB0106 is a 6-bit level translator that translates the 1.5-V interface to communicate with 3-V modem codec.
The total required HD_audio bus is 5 bits and may require only 4 bits.

I2CThe major benefit of the TCA6408 device is its wide VCC range. It can operate from 1.65-V to 5.5-V on the P port side and on the SDA/SCL side. This allows the TCA6408 to interface with next-generation microprocessors and micro- controllers on the SDA/SCL side, where supply levels are dropping down to conserve power. In contrast to the dropping power supplies of microprocessors and microcontrollers, some PCB components such as LEDs remain at a 5-V power supply.
The major benefit of the TCA8418 device is it frees up the processor from having to scan the keypad for presses and releases. This provides power and bandwidth savings. The TCA8418 is also ideal for usage with processors that have limited GPIOs.

Voltage-Level .TranslationARM embedded processor operating voltages continue to drop, depending on the process, level of integration and more functions such as power saving.
Some processor I/Os need logic-level translators to communicate between 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V and 5-V nodes.
Netbook applications must support VGA video output. Most 8-bit DAC logic interfaces are 3 V and need a 24-bit level translator to communicate with processors that have 1.8-V or 2.6-V incompatible logic levels.
In the same way, SDIO is a 3-V standard push-pull/ open-drain I/F for memory cards that also needs 6-bit level translators. The TXS0206 is a specific 6-bit translator that integrates ESD, an EMI filter and pull-up/down resistors to save space.

TPS2294x .Load .SwitchesTPS2294x load switches provide protection to systems and loads in high-current conditions. The devices contain a 400-mΩ current-limited P-channel MOSFET that can operate over an input voltage range of 1.62 V to 5.5 V. Current is prevented from flowing when the MOSFET is off. The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage control signals. The TPS2294x includes thermal shutdown protection that prevents damage to the device when a continuous over- current condition causes excessive heating by turning off the switch.

TI low-dropout (LDO) linear regulators are low-quiescent- current devices with excellent line and load transient performance. These LDOs are designed for power-sensitive applications. A precision bandgap and error amplifier provide up to 1 percent accuracy. Low output noise, a very high power-supply rejection ratio (PSRR) and low dropout voltage make this series of devices ideal for most battery-operated handheld equipment. All device versions have thermal shutdown and current limit for safety.

The PCA9555 consists of two 8-bit Configuration (input or output selection), Input Port, Output Port, and Polarity Inversion (active high or active low operation) registers. At power on, the I/Os are configured as inputs. The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding Input or Output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master.
Advantages• Each port is assigned with 4 GPIO ports for peripheral
uses.
Benefits• The PCA9555 GPIO port is integrated with pull-up resistors
and safe, discrete, external pull-up resistors.

I2C .and .SMBus .InterfaceAs more features and processing requirements are added to computing applications, the limited number of GPIOs on microprocessors is becoming restricting. By implementing I2C I/O expanders from TI, designers can use the GPIOs for important functions and the I2C I/O expanders for other duties.
Designers can also use I2C MUXes and switches to resolve address conflicts on the I2C bus. In some server designs, multiple SFPs with the same I2C address are used, or there can be multiple temperature sensors with the same I2C address. I2C MUXes and switches facilitate smooth operation by selecting which device the master or processor should communicate with at the appropriate time. I2C LED drivers are also essential for lighting functions such as indicator lights.

TPDxE001
An ESD strike is a constant threat to device reliability and functionality. Many low-voltage core chips or system ASICs offer only device-level human-body model (HBM) ESD protec-tion, which does not address the risks of system-levelESD strikes.
TI's stand-alone ESD solutions provide a space-saving and cost-effective solution to protect system interconnects from external ESD strikes. The TPD product family from TI provides IEC 61000-4-2 level ESD protection, with solutions for multiple external interfaces, including video, audio and serial data transfer. TI's family of ESD devices meet require-ments for low-power, small-footprint applications.
Advantages• System-level ESD protection for high-speed applications:
• ±8-kV IEC 61000-4-2, contact discharge.• ±15-kV IEC 61000-4-2, air-gap discharge.
• Less than 1.5-pF I/O pin capacitance.• Ultra-low 1-nA leakage current.• Operating supply voltage range: +0.9 V to +5.5 V.• Space-saving packages: DQA, DRY, DRL, DRS, DRT
and DSM.

Blood pressure monitors can use the Korotkoff, oscillometric or pulse-transit-time methods to measure blood pressure, while a thermometer uses a thermopile/thermistor combination to measure temperature. It is common to use an op amp to condition these types of signals before interfacing them with the microcontroller.

Audio .Signal .RoutingOne of the most common applications for analog switches is signal routing. This may be routing from one source to multiple destinations or from several sources to a single destination. A single-pole, double-throw analog switch can be used for either situation. For example, the switch could be used to reroute the output of the audio power amplifier to two different speakers. Another common application is switching from an audio amplifier in the baseband of a mobile to an audio power amplifier for higher power output.
Applications• DeMUX internal/external speakers• MUX audio power amplifiers• Low-power routing (<100 mA)• Amplifier gain adjustment

Configurable Little LogicLittle Logic devices are needed on handsets to implement simple logic functions, signal conditioning or bug fixing. With TI’s configurable Little Logic devices, a single device can be configured to perform as many as nine different logic func-tions. This reduces costs because only a single device, rather than multiple logic parts, needs to be qualified, sourced and inventoried.

ESD/EMI .Protection
Protected
Circuit
I/O I/O
TPDxE001
For any external interface connector port, an ESD strike is a constant threat to device reliability. Many low-voltage core chip or system ASICs offer only device-level human-body-model (HBM) ESD protection, which doesn’t address system-level ESD. A stand-alone ESD is a space- and cost-effective solution to protect system interconnects from external ESD strikes.
Advantages• System-level ESD protection for high-speed applications:
• ±8-kV IEC 61000-4-2, contact discharge.• ±15-kV IEC 61000-4-2, air-gap discharge.
• Less than 1.5 pF I/O pin capacitance.• Ultra-low 1-nA leakage current.• Operating supply voltage range: +0.9 V to +5.5 V.• Space-saving packages: DRY, DRL, DRS and RSF.
Benefits• System-level ESD protection for high-speed interconnects.• Low capacitance suitable for USB 2.0 high-speed devices.• Ultra-low 1-nA leakage current enables precision analog
measurements like a glucose meter.• VCC pin allows devices to work as a transient suppressor.

Keypad .ControlKeypad control is one of the new application areas for I2C I/O expanders. It is useful in end applications like PDA phones that may need more than one keypad controller. For example, some PDA phones include a software keypad and a hardware keypad. In these cases, the processor can support one key-pad and the second keypad can be controlled by an I2C I/O expander like the TCA6408A. The TCA6408A can also be used in portable medical devices where the microcontroller is overloaded with several tasks. Here, the keypad function can be transferred to the I2C I/O expander, which can then support the few keys required in this application.
Advantages• Operating power-supply voltage range of 1.65 V to 5.5 V.• Allows bidirectional voltage-level translation and GPIO
expansion between:• 1.8-V SCL/SDA and 1.8-V, 2.5-V, 3.3-V or 5-V P port.• 2.5-V SCL/SDA and 1.8-V, 2.5-V, 3.3-V or 5-V P port.• 3.3-V SCL/SDA and 1.8-V, 2.5-V, 3.3-V or 5-V P port.• 5-V SCL/SDA and 1.8-V, 2.5-V, 3.3-V or 5-V P port.
• I2C to parallel port expander.• Low standby current consumption of 1 µA.

Fun .Light .DisplayThe TCA6507 is a 7-bit LED dimmer for a two-line bidirection-al (I2C) bus designed to control (or dim) LEDs via the I2C inter-face (serial clock [SCL]/serial data [SDA]). Without this device, the microprocessor or microcontroller must be actively involved in turning on and off the LEDs (per the required dim ming rate), which uses valuable processor time and overloads the I2C bus. The TCA6507 alleviates this issue by limiting the number of operations the processor requires to blink the LEDs, thus helping to create a more efficient system.
Advantages• Seven LED driver outputs with on, off, blinking and
fading at programmable rates.• Supports simultaneous brightness control and blink modes.• Open-drain outputs that directly drive LEDs to 40-mA max.• Configurable into two independent banks of LED drivers.• Widely programmable blink rates, fade-on and fade-off
rates, and maximum intensity.• LED intensity set with pulse-width modulation (PWM).• Outputs not used as LED drivers can be used as general-
purpose open-drain outputs.• 16 steps of maximum intensity control from fully off to
fully on states.
• 256 intensity levels during fade on or fade off for perceived smooth transition.
• Operating power-supply voltage range of 1.65 V to 3.6 V.

Typical .ESD/EMI .Filter .Locations
Because electrostatic discharge (ESD) is common in electronic circuits, a device that provides protection from the undesirable effects of ESD must be included in the circuit design. Designing advanced ESD protection structures is becoming more and more challenging with the system bus and I/O operating more often in high-speed mode.

TPS2290x .Load .SwitchesTPS2290x load switches are ultra-small, low ON resistance (ron) load switches with controlled turn on. The devices contain a P-channel MOSFET that operates over an input voltage range of 1.0 V to 3.6 V. The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage control signals. In TPS22902 and switches TPS22902B and TPS22904, a 120-Ω on-chip load resistor is added for output quick discharge when the switch is turned off.

TPS2294x .Load .SwitchesTPS2294x load switches provide protection to systems and loads in high-current conditions. The devices contain a 400-mΩ current-limited P-channel MOSFET that can operate over an input voltage range of 1.62 V to 5.5 V. Current is prevented from flowing when the MOSFET is off. The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage control signals. The TPS2294x includes thermal shutdown protection that prevents damage to the device when a continuous over- current condition causes excessive heating by turning off the switch.

TI devices are designed for LED displays and LED lighting applications with constant-current control and open-load, shorted-load, and over-temperature detection. These LED drivers provide great flexibility and device performance; they need an 8-bit, 16-bit or 24-bit shift register and data latches, which convert serial input data into a parallel output format. At the output stage, regulated current ports are designed to provide uniform and constant current for driving LEDs.
Applications• Monocolor, multicolor, full-color LED displays• Monocolor, multicolor LED signboards• Display backlighting• Multicolor LED lighting applications

TI low-dropout (LDO) linear regulators are low-quiescent- current devices with excellent line and load transient performance. These LDOs are designed for power-sensitive applications. A precision bandgap and error amplifier provide up to 1 percent accuracy. Low output noise, a very high power-supply rejection ratio (PSRR) and low dropout voltage make this series of devices ideal for most battery-operated handheld equipment. All device versions have thermal shutdown and current limit for safety.

lI2C .Control
As more features and processing requirements are added to applications such as LED control and camera interfaces in handsets, the limited number of GPIOs on microprocessors is becoming restricting. By implementing I2C I/O expanders from TI, designers can use the GPIOs for important functions and the I/O expanders for other duties, like temperature sensing and keypad communications.

For any external interface connector port, an ESD strike is a constant threat to device reliability. Many low-voltage core chip or system ASICs offer only device-level human-body-model (HBM) ESD protection, which doesn’t address system-level ESD. A stand-alone ESD solution is a space- and cost-effective solution to protect system interconnects from external ESD strikes.
Advantages• System-level ESD protection for high-speed applications:
• ±8-kV IEC 61000-4-2, contact discharge.• ±15-kV IEC 61000-4-2, air-gap discharge.
• Less than 1.5-pF I/O pin capacitance.• Ultra-low 1-nA leakage current.• Operating supply voltage range: +0.9 V to +5.5 V.• Space-saving packages: DRY, DRL, DRS and RSF.
Benefits• System-level ESD protection for high-speed interconnects.• Low capacitance suitable for USB 2.0 high-speed devices.• Ultra-low 1-nA leakage current enables precision analog
measurements like a glucose meter.• VCC pin allows devices to work as a transient suppressor.

TPS2294x .Load .SwitchesTPS2294x load switches provide protection to systems and loads in high-current conditions. The devices contain a 400-mΩ current-limited P-channel MOSFET that can operate over an input voltage range of 1.62 V to 5.5 V. Current is prevented from flowing when the MOSFET is off. The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage control signals. The TPS2294x includes thermal shutdown protection that prevents damage to the device when a continuous over- current condition causes excessive heating by turning off the switch.

As operating voltage levels in microprocessors continue to drop, a void may be created between peripheral devices and processors that disrupts interfacing between them. TI’s translators enable communication between incompatible I/Os, with level translation between the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V and 5-V nodes.

Maintenance and Control: I2C I/O Expansion, Switches and Buffers
Applications• I2C bus isolation• LEDcontrols• Temperaturesensing• Fancontrols
Designers can make better use of their scarce GPIOs by using TI’s I2C I/O expanders and multiplexers to time-share multiple peripherals to a single I2C port. For example, I/O expanders and multiplexers can be used to monitor and control a total system by taking advantage of the already available I2C bus.
Designers can also use I2C MUXes and switches to resolve address conflicts on the I2C bus. In some server designs, multiple SFPs with the same I2C address are used, or there can be multiple temperature sensors with the same I2C address. I2C MUXes and switches facilitate smooth operation by selecting which device the master or processor should communicate with at the appropriate time.
Advantages• ResolvesI2C address conflicts• Processorpinsavings• Improvedboardrouting• Reducedboardspace

TI devices are designed for LED displays and LED lighting applications with constant-current control and open-load, shorted-load, and over-temperature detection. These LED drivers provide great flexibility and device performance; they need an 8-bit, 16-bit or 24-bit shift register and data latches, which convert serial input data into a parallel output format. At the output stage, regulated current ports are designed to provide uniform and constant current for driving LEDs.
Applications• Monocolor, multicolor, full-color LED displays• Monocolor, multicolor LED signboards• Display backlighting• Multicolor LED lighting applications

One of the most common applications for switches is routing video signals. A typical television or other video system may need the ability to switch between multiple sources to a single receiver. This is a cost savings, as a single receiver can essentially be expanded into two or more ports with a relatively inexpensive video switch. Each video switch has a specific application depending on its characteristics. The most common applications are component video, composite video, S-video and emerging HDMI. HDMI is a fully digital interface that includes high-definition video and 5.1 audio.
Advantage• Expand a single video receiver into multiple video
receivers to handle multiple sources.

Audio/Video .Input .Multiplexer/Port .ExpansionOne of the most common applications is to switch multiple video input types to the video controller. Depending on the video bandwidth difference, the right video switch has to be selected correctly.
PC VGA video input and analog standard components (HDTV) are common video inputs to LCD monitor display, media display and LCD TV. It needs a 3-bit high-bandwidth SPDT to switch the desired input to a video controller.
HDVI, DVI and DisplayPort are standard digital video types using the high data rate differential signal. They require high-speed FET switches.

As the video chipset becomes increasingly more complex, more pins on a typical video controller are being used by new features offered in that chipset. At the same time, reducing the number of GPIOs that control external devices such as video switches, receivers and other peripherals helps reduce the video chipset’s cost. I2C I/O expanders allow for the expansion of these GPIOs when more are needed.
Applications• Processor pin savings• Improved board routing• Reduced board space

LCD/PDP .Digital .TVThe I2C bus is used in a wide range of applications because it is simple and quick to use. It consists of a two wire communication bus that supports bidirectional data transfer between a master and several slaves. The master or processor controls the bus – in particular, the serial clock (SCL) line. Data is transferred between the master and slave through a serial data (SDA) line.

TI offers commodity power devices managing different voltage requirements of 9 V, 5 V, 3.3 V and 2.5 V.
The TLV1117 is designed to be stable with tantalum and aluminum electrolytic output capacitors having an ESR between 0.2 Ω and 10 Ω. Unlike pnp-type regulators, in which up to 10 percent of the output current is wasted as quiescent current, the quiescent current of the TLV1117 flows into the load, increasing efficiency.

HDMI .and .DVI .InterfacesHDMI and DVI interfaces are high-data-rate digital-differential video inputs. They need a lower CIN ESD to reduce distortion and improve system reliability.
HDMI has a 4-pair (8-bit) high-speed TMDS, 0.8-pF CIN and 5-V level low-speed signals of DDC (SDA, SCL), HPD and CEC. Because most HDMI receiver chips operate at 3.3 V it also needs a level shifter between the connector and controller.
The TPD12S520 is an integrated 12-bit system ESD protector that has a 4-bit optional level shifter for DDC, HPD and CEC signals.
The TPD4S009/TPD4S010 and TPD8S009 are designed for high-speed main link by 4-bits and 8-bits, with lower CIN values.

Analog .Signal .RoutingOne of the most common applications for analog switches is signal routing. This may be routing from one source to multiple destinations or from several sources to a single destination. A single-pole, double-throw analog switch can be used for either situation. For example, the switch could be used to select differ-ent gain settings on an operational amplifier.
Applications• DeMUX inputs for microcontrollers• Op amp gain adjustment• Op amp filter selection

TI devices are designed for LED displays and LED lighting applications with constant-current control and open-load, shorted-load, and over-temperature detection. These LED drivers provide great flexibility and device performance; they need an 8-bit, 16-bit or 24-bit shift register and data latches, which convert serial input data into a parallel output format. At the output stage, regulated current ports are designed to provide uniform and constant current for driving LEDs.
Applications• Monocolor, multicolor, full-color LED displays• Monocolor, multicolor LED signboards• Display backlighting• Multicolor LED lighting applications

TI low-dropout (LDO) linear regulators are low-quiescent- current devices with excellent line and load transient performance. These LDOs are designed for power-sensitive applications. A precision bandgap and error amplifier provide up to 1 percent accuracy. Low output noise, a very high power-supply rejection ratio (PSRR) and low dropout voltage make this series of devices ideal for most battery-operated handheld equipment. All device versions have thermal shutdown and current limit for safety.
Applications• Wireless handsets• Smartphones, PDAs• MP3 players• ZigBee® networks• Bluetooth® devices• Li-Ion operated handheld products• WLAN and other PC add-on cards
