Si535x-B20QFN-EVB S i 5 3 5 0 / 5 1 2 0 - Q F N E V A L U A T I O N B O A R D U S E R ’ S G UI DE Description Features The Si535x-B20QFN-EVB is used for evaluating the Si5350/51 any-frequency, 0.0025–200 MHz CMOS clock generator + VCXO. 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 Functional Block Diagram Vreg* Jumper Selectable Vreg 1.8 V (VDDO only) / 2.5 V / 3.3 V Vreg* VReg VReg VReg VDD VDDO0 CLK0 CLK1 XTAL VDDO1 CLK2 CLKIN Si5350/51 CLK3 VDDO2 VC CLK4 CLK5 I2C I2C Bus VDDO3 CLK6 CLK7 MCU USB Connector Rev. 0.3 7/15 Status LEDs Reset Switch Copyright © 2015 by Silicon Laboratories Si535x-B20QFN-EVB Si535x-B20QFN-EVB 1. Functional Block Diagram Figures 1 and 2 highlight the main features of the EVB. The onboard MCU is responsible for programming the Si535x timing IC, measuring the device's current consumption reported in the ClockBuilder™ Desktop, 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 I2C master. The Si5350 device on this board is a hybrid of the Si5350/51 A, B, and C variants. It can run in stand-alone asynchronous mode (Si5350/51A) using the onboard 27 MHz XTAL (Y1), or it can be synchronized to an external clock using the CLKIN SMA connector or test points (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. Figure 1.

Jumpers The following jumpers are available on the evaluation board: VDD—Connects the Si5350/51 pin to the VDD voltage regulator (normally installed). 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). VDD 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. SCL—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. SDA—Connects 3. Status LEDs There 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 Inputs The EVB can operate in asynchronous mode using the onboard 27 MHz crystal, synchronous mode using an external CMOS clock source, or both modes. An SMA connector and test points are provided to interface an external clock source to CLKIN. Additionally, in the Si5350/51B mode, VC input can be applied to either the VC test point or SMA connection. 5. Clock Outputs Outputs can be measured using either SMA cables attached directly to an 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. 4 Rev. 0.3 Si535x-B20QFN-EVB 6. Software Guide The evaluation kit software toolset can be downloaded from www.silabs.com/Si5351-EVB. The toolset consists of the following two applications: ClockBuilder Register Desktop—Used to set up and evaluate the part and to save custom register map files. Programmer—Used to program individual registers on the evaluation board DUT. 6.1. Quick Start 1.
