The FPGA is the PHY

Abstract

We recently developed an FPGA-based 10/100/1000BASE-FX Ethernet PHY for one of our customers, as part of a fibre optic Ethernet link.

Implementing this in FPGA meant that both the financial and physical space costs of an extra, external PHY chip could be avoided, saving valuable space on the system PCB.

The PHY supports 10, 100 and 1000 Mbit/s connections including auto-negotiation, and is directly interfaced to an SFP transceiver.
