Notes to
(1) ATX PLLs do not have dedicated refclk pins.
(2) For more information, refer to
(3) For more information, refer to
(4) For better jitter performance, Altera strongly recommends using the refclk0 and refclk1 pins of the transceiver block located immediately
(5) Lowest number indicates best jitter performance.

Receiver clock data recoveries (CDRs), CMU PLLs (when the CMU channel is
configured as a CMU) and ATX PLLs can derive the input reference clock from one of
the sources listed in
When a CMU channel is configured as a channel, its CMU PLL acts as a receiver CDR
and can derive the input reference clock sources 2 through 5 listed in the
You can also use the refclk pin of the other CMU channel within the transceiver
block as a clock source as long as the other CMU channel is not configured as a
Receiver only or Receiver and Transmitter channel. For example, the CMU0 PLL can
derive its input reference clock from the refclk1 pin if the CMU1 channel is not
configured as a Receiver only or Receiver and Transmitter channel.
When a CMU channel is configured as a channel, its refclk pin is used to receive
serial input data. As a result, the refclk pin is not available to provide the input
reference clock.
