Note: The clocks described here are separate and not synchronous to the clock provided by the USB host interface.
200 MHz Oscillator (Fabric)
A fixed-frequency, 200 MHz, low-jitter oscillator is included on-board and outputs LVDS to the FPGA on bank 34. The Kintex-7 FPGA can produce a wide range of clock frequencies using the on-chip DCM and PLL capabilities. An external termination resistor is provided for this clock so internal termination is not necessary.

Details of the oscillator are shown below. Please note that this specific model number is subject to change and an approximate substitute may be used depending on availability.
|OSCILLATOR TYPE||SAW Clock Oscillator|
|DETERMINISTIC JITTER||0.2 ps typical|
|1 SIGMA JITTER||2 ps typical|
|PEAK TO PEAK JITTER||20 ps typical|
100 MHz Oscillator (Transceivers)
A second 100 MHz oscillator is available to the transceiver portions of the FPGA as a reference.
