If we use external clocks for both the Pattern Generator and Error Detector parts, can we run them at different data rates?
It would be more straight-forward to provide the PG (TX) with a 10 GHz clock (for 10 Gb/s data) and then use the 1:4 demux and provide the ED (RX) with a 2.5 GHz clock (measuring 2.5 Gb/s data). Click on the question for additional information.
