Figure 1–22. Transmitter Output Buffer
This section describes the Arria II GX and GZ receiver channel datapath architecture.
The sub-blocks in the receiver datapath are described in order from the receiver input
buffer to the RX phase compensation FIFO buffer at the FPGA fabric-to-transceiver
interface.

This section describes the receiver PMA modules, which consists of the receiver input
buffer, CDR, and deserializer.
The rx_analogreset signal resets all modules in the receiver PMA block. For more
information about this signal, refer to the
Devices
Receiver-detect capability to support PCIe functional mode—This circuit detects if
there is a receiver downstream by sending out a pulse on the common mode of the
transmitter and monitoring the reflection. For more information, refer to
