Combining Channels Configured in Basic (PMA Direct) ×N Configuration with Non-Basic
(PMA Direct) Configurations
The Quartus II software only allows a combination of a transceiver channel instances
configured in Basic (PMA Direct) ×N mode with instances in non-Basic (PMA Direct)
configurations; for example, GIGE and SDI.
Consider the example design listed in
combining a Basic (PMA Direct) ×N configuration with a non-Basic (PMA Direct)
configuration using a CMU PLL.
Note that channel 5 in inst0 is placed in transceiver block 1 and receives the
high-speed clock through the ×N_Top clock line.
Some of the channels in transceiver block 1 receive their high-speed clock from the
×N_Bottom clock line. Because the ×N_Top and ×N_Bottom lines are separate, this
scenario is allowed. To understand the clock multiplexer on the ×N clock lines,
refer to
