COMMUNICATION MODULE AND TRANSCEIVER INTEGRATED CIRCUIT TO REDUCE WIRE AREA COMMUNICATION MODULE AND TERMINALS TO BE INSTALLED AT TRANSCEIVER INTEGRATED CIRCUIT

摘要

PURPOSE: A communication module and a transceiver integrated circuit to reduce a wire area in a communication module and terminals to be installed at a transceiver integrated circuit are provided to reduce a wire area in a communication module by not using a dedicated terminal or wire for electric waves for each clock. CONSTITUTION: A bus(3) includes a data bus(3a) and a clock bus(3b). The data bus(3a) is used in common for either electric waves of data MDIO(Management Data Input/Output) conforming to a standard of an MDIO interface performed between a host controller IC(Integrated Circuit)(40) and a transceiver IC(1), or electric waves of data SDA conforming to a standard of I2C(Inter IC) performed between the transceiver IC(1) and a peripheral IC(2). The clock bus(3b) is used in common for either electric waves of clock MDC conforming to the MDIO interface performed between the host controller IC(40) and the transceiver IC(1), or electric waves of clock SCL conforming to a standard of I2C performed between the transceiver IC(1) and the peripheral IC(2).
