12. Transceivers in Intel Agilex® 5 FPGAs and SoCs

The Intel Agilex® 5 FPGAs and SoCs are equipped with NRZ transceivers optimized for a wide variety of applications, ranging from 1 Gbps to 28.1 Gbps NRZ.

The monolithic GTS transceivers in Intel Agilex® 5 FPGAs and SoCs enable low latencies for edge or mid-range FPGA applications. For long reach backplane-driving applications, the devices use advanced adaptive equalization circuits to equalize system loss.

All Intel Agilex® 5 FPGA GTS transceiver channels are equipped with these blocks:

  • Dedicated PMA—provides primary interfacing capabilities to physical channels.
  • Hardened PCS—supports 64b/66b encoding and decoding functions, data scrambling, block alignment, and gearboxing functions.
  • FEC—Firecode FEC for 10/25 GbE BASE-KR/CR applications and Reed Solomon FEC.

A single PMA–PCS channel with independent clock domains forms each GTS transceiver channel. Using a highly configurable clock distribution network, you can configure various bonded and non-bonded data rate within each GTS transceiver bank.
