Intel Arria 10 User Manual

5. Arria 10 Transceiver PHY Architecture
5.1. Arria 10 PMA Architecture
The Physical Medium Attachment (PMA) acts as the analog front end for the Arria 10
transceivers.
The PMA receives and transmits high-speed serial data depending on the transceiver
channel configuration. All serial data transmitted and received passes through the
PMA.
5.1.1. Transmitter
The transmitter takes the parallel data and serializes it to create a high-speed serial
data stream. The transmitter portion of the PMA is composed of the transmitter
serializer and the transmitter buffer. The serializer clock is provided from the
transmitter PLL.

5.1.1.1. Serializer
The serializer converts the incoming low-speed parallel data from the transceiver PCS
or FPGA fabric to high-speed serial data and sends the data to the transmitter buffer.
The channel serializer supports the following serialization factors: 8, 10, 16, 20, 32,
40, and 64.
