Each transceiver channel consists of a transmitter and a receiver datapath. Each
datapath is further structured into the following:
■
■
Outbound parallel data from the FPGA fabric flows through the transmitter PCS and
PMA, is transmitted as serial data. Received inbound serial data flows through the
receiver PMA and PCS into the FPGA fabric. The transceiver supports the following
interface widths:

Physical media attachment (PMA)—includes analog circuitry for I/O buffers,
clock data recovery (CDR), serializer/deserializer (SERDES), and programmable
pre-emphasis and equalization to optimize serial data channel performance.
Physical coding sublayer (PCS)—includes hard logic implementation of digital
functionality within the transceiver that is compliant with supported protocols.
FPGA fabric-transceiver PCS—8, 10, 16, or 20 bits
PMA-PCS—8 or 10 bits
