Clocks
An on-board oscillator provides a free running clock to the FPGA and CPLD. The
default is a 50Mhz oscillator but other frequencies can be provided upon request to
Sundance.
An external clock input/outptut is provided to the Virtex II FPGA via a 50 ohms MMBX
coax-connector.
These clocks can be de-skewed by the FPGA DCMs or output to other TIMs to
synchronise TIMs together.
