Systems and methods for operating according to an auto-negotiated data rate in a network switch

摘要

A network switch including a physical layer device and a media access controller. The physical layer device includes an auto-negotiation circuit configured to negotiate a first data rate for transmission of data between the physical layer device and a network client external to the network switch, and a first serializer interface configured to receive the first data rate from the auto-negotiation circuit. The media access controller includes a second serializer interface. The first serializer interface of the physical layer device is configured to, based on the negotiated first data rate received from the auto-negotiation circuit, selectively replicate portions of data received from the network client, and transmit the data to the second serializer interface of the media access controller at a second data rate regardless of the first data rate negotiated between the auto-negotiation circuit and the network client. The first data rate and the second data rate are different.

1. A network switch, comprising:
a physical layer device including
an auto-negotiation circuit configured to negotiate a first data rate for transmission of data between the physical layer device and a network client external to the network switch, anda first serializer interface configured to receive the negotiated first data rate from the auto-negotiation circuit; and a media access controller including a second serializer interface,
wherein the first serializer interface of the physical layer device is configured to (i) based on the negotiated first data rate received from the auto-negotiation circuit, selectively replicate portions of data received from the network client, and (ii) transmit the data to the second serializer interface of the media access controller at a second data rate regardless of the first data rate negotiated between the auto-negotiation circuit and the network client, wherein the first data rate and the second data rate are different.
