Signal driving method and communication device

Abstract

The embodiment of the invention provides a signal driving method and a communication device, which relate to the technical field of communication. The communication device includes a control chip, a complex programmable logic device and multiple physical lay chips. The complex programmable logic device includes a plurality of logic groups. The control chip and the plurality of physical layer chipsall include management interfaces, a plurality of logic groups are commonly used for providing a plurality of output voltages corresponding to the operating voltages of the plurality of management interfaces, and the management interface of each of the control chip and the plurality of physical layer chips is connected to one corresponding logic group that provides an output voltage correspondingto an operating voltage of the management interface. Upon receiving the first clock signal and the first data signal output from the control chip, the first clock signal and the first data signal aredriven to obtain the second clock signal and the second data signal, and the second clock signal and the second data signal are outputted to a plurality of physical layer chips corresponding to the plurality of logic groups, so that the driving capability is enhanced and the hardware cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular, to a signal driving method and a communication device. Background technique [0002] MDIO (Management Data Input / Output, management data input and output) is defined by IEEE through several clauses of Ethernet standard IEEE 802.3 and 802.3ae. It is a simple two-wire serial interface that can connect management devices (such as microprocessors) ) interface with a transceiver with management functions, such as a multiport Gigabit Ethernet transceiver or a 10GbE XAUI transceiver, to control the transceiver and collect status information from the transceiver. The MDIO interface is an important interface for control and status information communication between the Ethernet MAC layer and the PHY layer. The timing of read and write operations must comply with the IEEE802.3 standard. The protocol stipulates that the MDIO interface can connect up to 32 physical layer devic...

Problems solved by technology

In the existing solutions, the driver chip Driver or MAC chip will face the situation of more than one driver, resulting in the actual driving capability on the MDIO bus is still weak; and adding the driver chip alone will also increase the hardware cost
