Si5350/51 EVALUATION BOARD USER’S GUIDE
Description
The Si535x-B20QFN-EVB is used for evaluating theSi5350/51 any-frequency, 0.0025–200 MHz CMOSclock generator + VCXO.The pre-soldered 20-QFN device can be configuredusing ClockBuilder Pro to emulate all available Si5350/51 package options, including 10-MSOP, 16-QFN, and20-QFN.
Features
ClockBuilder Pro configurable, allowing quick frequency plan analysis
Fully-powered from a single USB port Onboard 27 MHz crystal for asynchronous operation SMA and test point hook for interfacing to an
external clock reference Jumper-selectable VDD and VDDOx allows device
to operate at 1.8 (VDDO only), 2.5, or 3.3 V Voltage supply jumpers provide easy access for use
with external supplies

1. Functional Block DiagramFigures 1 and 2 highlight the main features of the EVB. The onboard MCU is responsible for programming theSi535x timing IC, measuring the device's current consumption reported in the ClockBuilder™ Pro EVB GUI,managing power, and controlling status LEDs. VDD and VDDO jumpers allow the option of choosing between 1.8(VDDO only), 2.5, and 3.3 V or powering the device with external supplies (see Section “2. Jumpers” for details).I2C jumpers allow the Si535x to be disconnected from the I2C bus, allowing external control from another I2Cmaster.The Si5350 device on this board is a hybrid of the Si5350/51 A, B, and C variants. It can be configured to emulatea 10-MSOP, 16-QFN, or 20-QFN device. It can run in stand-alone asynchronous mode (Si5350/51A) using theonboard 27 MHz XTAL (Y1), or it can be synchronized to an external clock using the CLKIN SMA connector or testpoints (Si5350/51C). It can also accept a VC input when in VCXO (Si5350/51B) mode.Note: EVBs labelled "REV 1.1" or "REV 1.2" are populated with rev A devices.

2. JumpersThe following jumpers are available on the evaluation board:
VDD—Connects the Si5350/51 pin to the VDD voltage regulator (normally installed).VDD VOLT_SEL—Allows user to select a VDD voltage of 2.5 V or 3.3 V (default 3.3 V).VDDOA—Connects the Si5350/51 pin to the VDDOA voltage regulator (normally installed).VDDOA VOLT_SEL—Allows user to select a VDDOA voltage of 1.8 (jumper removed), 2.5, or 3.3 V
(default).VDDOB—Connects the Si5350/51 pin to the VDDOB voltage regulator (normally installed).VDDOB VOLT_SEL—Allows user to select a VDDOB voltage of 1.8 (jumper removed), 2.5, or 3.3 V
(default).VDDOC—Connects the Si5350/51 pin to the VDDOC voltage regulator (normally installed).VDDOC VOLT_SEL—Allows user to select a VDDOC voltage of 1.8 (jumper removed), 2.5, or 3.3 V
(default).VDDOD—Connects the Si5350/51 pin to the VDDOD voltage regulator (normally installed).VDDOD VOLT_SEL—Allows user to select a VDDOD voltage of 1.8 (jumper removed), 2.5, or 3.3 V
(default).
SCL—Connects the Si5350/51 SCL pin to the I2C bus from the MCU. Removing the jumper breaks the connection to the MCU and allows the user to feed in an external I2C signal to the device.
SDA—Connects the Si5350/51 SDA pin to the I2C bus from the MCU. Removing the jumper breaks the connection to the MCU and allows the user to feed in an external I2C signal to the device.
EXT POWER—Allows user to select between 5 V USB supply and 5 V external supply on J17. See Figure 1 for jumper locations.
3. Status LEDsThere are three status LEDs on the evaluation board:
RDY (Green)—Indicates that the EVB is operating normally. This LED should always be on.BUSY (Green)—Indicates that the on-board MCU is communicating with the device and/or the USB host.INTR (Red)—Indicates device or EVB fault condition (also on when DUT hasn't been programmed).
4. Clock InputsThe EVB can operate in asynchronous mode using the onboard 27 MHz crystal, synchronous mode using anexternal CMOS clock source, or both modes. An SMA connector and test points are provided to interface anexternal clock source to CLKIN. Additionally, in the Si5350/51B mode, VC input should be applied to either the VCtest point or SMA connection.
5. Clock OutputsOutputs can be measured using either SMA cables attached directly to a high-input impedance oscilloscope(recommended) or with high impedance probes at the output clock test loops (TP53-TP60).Clock voltage levels can be 1.8, 2.5, or 3.3 V depending on the VDDOx VOLT_SEL jumper selection.

6. Software GuideThe Si535x-B20QFN-EVB is fully compatible with ClockBuilder Pro. This software can be used to program the pre-soldered hybrid Si5350/51 device to emulate any type of Si5350/51 part, including A/B/C variants, in 10-MSOP, 16-QFN, or 20-QFN packages.To program the device, just connect the Si535x-B20QFN-EVB to a computer running ClockBuilder Pro using theprovided USB Cable. With the ClockBuilder Pro software opened and the EVB connected, a "Si535x EVB" willshow up on the main ClockBuilder Pro Wizard page.
Figure 3. ClockBuilder Pro Wizard with the Si535x EVB ConnectedFrom this page, either open a default EVB plan, open an existing Si535x A/B/C ClockBuilder Pro project file usingthe Open Project button, or create a new Si535x A/B/C project file using the Create New Project button. Once aproject file is opened, it can be written to the EVB in the Design Dashboard. When a 10-MSOP or 16-QFN projectis written to the EVB, an additional GUI will pop-up to show which CLK outputs on the EVB apply to that packagetype.Once a configuration has been finalized, a project file can either be used to create a custom-orderable Si5350/51part number, or the register file can be exported for easy in system volatile programming.The ClockBuilder Pro EVB GUI can also be used to view or modify individual Si5351 registers as well as monitorthe device's power consumption.
