RF Clocking¶
The following figure shows a high-level block diagram for the clocking network:
At boot the RFSoC 4x2 the LMK will be programmed to provide a 122.88 MHz reference to the PL and a 245.76 MHz reference for the ADC and DAC LMX. The LMX PLLs are programmed to provide a reference of 491.52 reference to the RFDC ADC and DAC tiles.
