Timing may not be met for higher data rates when transceiver channels are
configured in Basic (PMA Direct) functional mode. To meet FPGA fabric-Transmitter
PMA interface timing above certain data rates, you may need to phase shift the
interface clock tx_clkout used to clock the transmitter user logic. To meet FPGA
fabric-Receiver hold time violations, you may have to modify the way data is
captured in the FPGA fabric.

Functional
This section describes the receiver PMA and PCS datapath clocking in supported
configurations. Receiver datapath clocking varies between non-bonded and bonded
channel configurations. It also varies with the use of PCS blocks, such as deskew FIFO
and rate matcher. This section describes the following:
■

■
Non-Bonded Channel Configurations
In non-bonded channel configurations, receiver PCS blocks of each channel are
clocked independently. Each non-bonded channel also has separate rx_analogreset
and rx_digitalreset signals that allow independent reset of the receiver PCS logic in
each channel.

Reset Control and Power Down in Stratix IV Devices
In non-bonded channel configurations, receiver channel datapath clocking has two
scenarios:

Non-Bonded Receiver Clocking Without Rate Matcher
The following functional modes have non-bonded receiver channel configuration
without rate matcher:
