This section describes the Arria II GX and GZ transmitter channel datapath
architecture. The sub-blocks in the transmitter datapath are described in order from
the TX phase compensation FIFO buffer at the FPGA fabric-to-transceiver interface to
the transmitter input buffer.
Figure 1–11
This section describes the transmitter PCS modules, which consists of the TX phase
compensation FIFO, byte serializer, and 8B/10B encoder.
The tx_digitalreset signal resets all modules in the transmitter PCS block.
For more information about the tx_digitalreset signal, refer to the
Power Down in Arria II Devices
TX Phase Compensation FIFO
This FIFO compensates for the phase difference between the low-speed parallel clock
and the FPGA fabric interface clock.
