Clock Oscillators
General (Fabric) Reference
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.

Transceiver Reference
A second 100 MHz oscillator is available to the transceiver portions of the FPGA as a reference.
