Chip-to-chip interface for 1000base-T gigabit physical layer device

Abstract

A physical layer interface including an auto-negotiation circuit configured to negotiate a first data transmission rate with a network client; a transceiver configured to communicate with the network client at the first data transmission rate; and a serializer interface configured to communicate with a media access controller at a second data transmission rate that is different than the first data transmission rate. The serializer interface includes a transmitter configured to replicate data received from the network client in response to the first data transmission rate being lower than the second data transmission rate.

Dependencies are inferred from the claim text.
