1.2.2. PHY Layer Transceiver Components

Transceivers in Arria® 10 devices support both Physical Medium Attachment (PMA) and Physical Coding Sublayer (PCS) functions at the physical (PHY) layer.

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
