Configuration
Combining Multiple Instances of Transmitter Only and Receiver Only
Configurations in Basic (PMA Direct) ×1 Mode
The Quartus II software allows you to combine instances of Transmitter Only and
Receiver Only configurations in Basic (PMA Direct) ×1 mode.
You can also combine Transmitter Only instances in non-Basic (PMA Direct) ×1
configuration (non-bonded only) and the Receiver Only instance in Basic (PMA
Direct) configurations (and vice versa) in the same physical channel. The combination
requirements of the instances in Basic (PMA Direct) ×1 configuration are similar to
that of non-Basic (PMA Direct) configuration. For more information, refer to the
“Combining Transmitter Channel and Receiver Channel Instances” on page
Combining Channels Configured in Basic (PMA Direct) ×1 with Non-Basic
(PMA Direct) Modes
You can combine a transceiver channel instance configured in Basic (PMA Direct) ×1
configuration with instances set up in non-Basic (PMA Direct) configurations (for
example, GIGE and SDI within the same transceiver block).
If the CMU PLL configuration for the Basic (PMA Direct) ×1 configuration and the
non-Basic (PMA Direct) configuration instances meet the requirements specified in
“Multiple Channels Sharing a CMU PLL” on page 3–5

these two instances. In addition, to share the same CMU PLL between the two
instances, you cannot enable the channel reconfiguration option in the instance setup
in non-Basic (PMA Direct) configuration.
