High speed signal drive circuit

A high speed signal drive circuit, comprising:

• a D-PHY (physical layer) drive signal generation module, a C-PHY (physical layer) drive signal generation module, a drive signal selection module and a multiplex drive module,
• wherein an output terminal of the D-PHY drive signal generation module and an output terminal of the C-PHY drive signal generation module are both connected to an input terminal of the drive signal selection module, and an output terminal of the drive signal selection module is connected to an input terminal of the multiplex drive module;
• the D-PHY drive signal generation module is configured to generate a D-PHY (physical layer) drive signal;
• the C-PHY drive signal generation module is configured to generate a C-PHY (physical layer) drive signal;
• and
• the drive signal selection module is configured to:
• receive the D-PHY drive signal or the C-PHY drive signal, and control a control switch of the multiplex drive module to be on and off based on the D-PHY drive signal or the C-PHY drive signal, whereby the multiplex drive module function as a D-PHY (physical layer) drive circuit or a C-PHY (physical layer) drive circuit,
• wherein the multiplex drive module comprises at least three drive sub-modules:
• each of the at least three drive sub-modules comprises eight control switches and eight adjustable resistors, each of four adjustable output resistors of the eight adjustable output resistors is connected to a termination power supply through a respective one of the eight controls switches, each of another four adjustable output resistors of the eight adjustable output resistors is connected to a grounding terminal through a respective one of the eight control switches, and terminals of all the adjustable output resistors, which are not connected to the control switches, are connected to each other to function as an output terminal.
