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

摘要

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.
