12. Transceivers in Agilex™ 5 FPGAs and SoCs
The monolithic GTS transceivers in 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 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.
