PHY Layer Transceiver Components
A PMA is the transceiver's electrical interface to the physical medium. The transceiver PMA consists of standard blocks such as:
- serializer/deserializer (SERDES)
- clock and data recovery PLL
- analog front end transmit drivers
- analog front end receive buffers
The PCS can be bypassed with a PCS-Direct configuration. Both the PMA and PCS blocks are fed by multiple clock networks driven by high performance PLLs. In PCS-Direct configuration, the data flow is through the PCS block, but all the internal PCS blocks are bypassed. In this mode, the PCS functionality is implemented in the FPGA fabric.
