Abstract

A high speed signal drive circuit includes a D-PHY drive signal generation module, a C-PHY drive signal generation module, a drive signal selection module and a multiplex drive module. 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. An output terminal of the drive signal selection module is connected to an input terminal of the multiplex drive module. The drive signal selection module controls control switches of the multiplex drive module to be on and off based on a D-PHY drive signal or a C-PHY drive signal, so that the multiplex drive module functions as a D-PHY drive circuit or a C-PHY drive circuit. Thus, dual functions of the D-PHY drive circuit and the C-PHY drive circuit can be realized.
