Use the edge combiner to generate output frequencies greater than 200 MHz. To use the Edge Combiner, set CH0_EDGE_COMB_EN (R3[3]) or CH1_EDGE_COMB_EN (R3[7]) to '1'. When using the edge combiner, both FODs must operate at the same exact frequency (that is, the divide values must match). The device handles this by automatically loading the divider values from FOD0 into FOD1 when either CHx_EDGE_COMB_EN bit is set to a '1'. SSC on FOD0 is not supported when using the edge combiner, and must not be enabled. Either of the FODs can still generate the LVCMOS REF_CLK output.
For proper edge combiner operation, the following conditions must be true:
