Abstract
A GPIO interface circuit compatible with output of MIPI signals, comprises a first CMOS signal output module (), an LVDS signal output module (), a second CMOS signal output module (). When an MIPI output enable input of the LVDS signal output module () is enabled and output enable inputs of the first and second CMOS signal output modules () are both disabled, a first and second pull-down modules () are in active state accordingly, and the LVDS signal output module () outputs a current signal to the first or second pull-down module () to ensure voltage of the first or second signal output be a preset voltage, which can achieve MIPI HS Mode output.
