Cypress Delivers Industry-Leading Flexible TimingSolutions for Next-Generation Consumer Devices
001-91135 Owner: PAJE High-Performance 4-PLL Clock Generator New Product Introduction (Customer)Rev *A
Consumer devices are becoming feature-rich and connectedThey integrate storage, media processing and connectivity to enhance the user experienceSo users can create, store and share digital media content anywhere and anytime
Sharing high-resolution media content requires faster data transfer standardsThe data storage transfer protocol has moved from SATA 1.0 to SATA 3.0Ethernet systems have migrated from 10 Gbps to 100 GbpsUSB 3.0 is replacing USB 2.0 for user connectivityData interconnect standards are moving from PCIe 1.0 to PCIe 3.0
Consumer devices must support multiple data standards, each with specific timing requirements
Consumer devices require highly integrated and flexible timing solutions

Terms You Will Hear TodayCycle-to-Cycle Jitter (ps)The maximum difference in a clock period between two adjacent clock cycles, measured over 1,000 clock cycles
Phase Noise (dBc/Hz)Noise power relative to clock signal power, measured in a 1Hz window centered at a given offset frequency from the clock signal
RMS Phase Jitter (ps) The integration of Phase Noise over a specified bandwidth, most commonly 12 kHz to 20 MHz (see below)
RMS Phase Jitter = , where fc is the clock frequency
Voltage Controlled Frequency Synthesis (VCFS)A method by which the frequency of a clock signal is varied based on a control voltage input

Terms You Will Hear TodayElectromagnetic Interference (EMI)A disturbance that affects an electrical circuit, often caused by electromagnetic radiation emitted by an external sourceClocks create electromagnetic radiation, because of their high frequency and periodic nature
Spread Spectrum (SS) ModulationA method used to vary the frequency of a clock signal to spread its energy across a wider frequency range, thus reducing EMI
Frequency Select A feature in a clock generator used to select a preprogrammed output frequency using external digital control pins Used also to selectively turn off the reference frequencies to certain peripherals to reduce power consumption

Design Problems Engineers FaceMultiple clocks in consumer devices increase the BOM cost and PCB areaUp to 12 reference clocks, including RTC1, may be required for the processors and peripherals (PCIe, USB, SATA, GbE)
High-frequency clocks produce enough EMI to violate regulatory emission standardsTraditional EMI-reduction solutions, such as ferrite beads and chokes, are expensive and add board spaceEMI problems threaten time-to-market because EMI testing is typically performed at the end of the development cycle
Consumer products require additional components to manage reference clocks Audio systems require Glitch-free clock switching to suppress burst noise2
Multifunction printers need to selectively turn off clocks to certain peripherals to reduce power consumptionConsumer devices with multiple systems-on-chip require their respective reference clocks to be in phase with each other
Cypress’s CY27410 4-PLL clock generator solves these problemsSaves board space by generating up to 12 programmable output frequencies on a single chip Reduces EMI using SS ModulationSimplifies system design with Glitch-free switching, Frequency Select and early/late clocks for phase control
Cypress’s high-performance clock generator is a single-chip solution that simplifies system design
