Introduction

Titanium™ transceivers consist of a physical medium attachment (PMA) and a physical coding sublayer (PCS). The PMA connects the FPGA to the lane, generates the required clocks, and converts the data from parallel to serial or serial to parallel. The PCS contains the digital processing interface between the PMA and the FPGA fabric. The PCS supports SGMII, 10GBase-KR, and PCIe Gen4 as well as PMA Direct. This user guide provides the specifications for the SGMII interface.
