refclk0 and refclk1 Pins
Each transceiver block has two dedicated refclk pins that you can use to drive the
CMU PLL, receiver CDR, input reference clock, or all three. Each of the two CMU
PLLs and four receiver CDRs within a transceiver block can derive its input reference
clock from either the refclk0 or refclk1 pin.
The refclk pins provide the cleanest input reference clock path to the CMU PLLs.
Altera recommends using the refclk pins to drive the CMU PLL input reference clock
for improved transmitter output jitter performance.
