2. Applications
The Si531x/2x Any-Frequency Precision Clocks have a comprehensive feature set, including any-frequency
synthesis, multiple clock inputs, multiple clock outputs, alarm and status outputs, hitless switching between input
clocks, programmable output clock signal format (LVPECL, LVDS, CML, CMOS), output phase adjustment
between output clocks, and output phase adjustment between all output clocks and the selected reference input
clock (phase increment/decrement). For more details, consult the Silicon Laboratories timing products website at
www.silabs.com/timing.
All six evaluation boards (EVBs) have an MCU (C8051F340) that support USB communications with a PC host.
For the pin controlled parts (Si5316, Si5322, and Si5323), the pin settings of the devices are determined by the
MCU and the PC resident software that is provided with the EVB. For the MCU controlled parts (Si5319, Si5324,
Si5325, Si5326, and Si5327), the devices are controlled and monitored through the serial port (either SPI or I²C). A
CPLD sits between the MCU and the Any-Frequency Precision Clock device that performs voltage level translation
and stores the pin configuration data for the pin controlled devices. Jumper plugs are provided so that the user can
bypass the MCU/CPLD to manually control the pin controlled devices. Ribbon headers and SMA connectors are
included so that external clock in, clock out, and status pins can be easily accessed by the user. For the MCU
controlled devices (Si5319, Si5324, Si5325, Si5326, and Si5327), the user also has the option of bypassing the
MCU and controlling the parts from an external serial device. On-board termination is included so that the user can
evaluate single-ended or differential as well as ac or dc coupled clock inputs and outputs. A separate DUT (Device
Under Test) power supply connector is included so that the Any-Frequency Precision Clocks can be run at either
1.8, 2.5 or 3.3 V, while the USB MCU remains at 3.3 V. LEDs are provided for convenient monitoring of key status
signals.
