A switching chip, network device and power consumption control method

Abstract

The invention discloses a switching chip, a network device and a power consumption control method. The switching chip includes a power-off module, a plurality of PCS units and a physical layer unit; the plurality of PCS units are connected with the physical layer unit and the physical layer unit respectively. The power shutdown module is connected; the PCS unit controls the power shutdown of the non-common SerDes interface in the unused state in the physical layer unit; the power shutdown module judges whether to Turn off the power supply of the public SerDes interface; the network device includes a switch chip and a processor that controls the switch chip, which solves the problem of the SerDes interface when the channel of a certain SerDes interface and the PCS is not in use in the prior art. Also be in power consumption state, cause the technical problem of power consumption waste.

Description

technical field [0001] The invention relates to the communication field, in particular to a switch chip, network equipment and a power consumption control method. Background technique [0002] In the field of communication, due to continuous improvement of transmission bandwidth, SerDes interfaces (SERializer / DESerializer, serializer / deserializer) have been widely used, and the number of SerDes interfaces is also increasing. Due to the implementation of a SerDes PHY (Physical Layer, physical layer) circuit, the power consumption of the SerDes interface is relatively large. Therefore, the low power consumption control of the SerDes interface has become one of the situations that must be considered in the low power consumption control of the communication chip. [0003] Now SerDes physical layer devices are designed in a multi-channel manner when designing, that is, multiple PCS (Physical Coding Sublayer, physical mask sublayer) are connected to one SerDes physical layer devi...

Problems solved by technology

[0005] The embodiment of the present invention provides a switching chip, a network device, and a power consumption control method to solve the problem in the prior art that when a certain SerDes interface and the channel of the PCS are not in use, the SerDes interface is also in a state of power consumption, resulting in failure wasteful technical issues
