UNISONIC TECHNOLOGIES CO., LTD CCVGA7C9 VGA OR DVI-I PORT COMPANION CIRCUIT  DESCRIPTION Preliminary TVS The UTC CCVGA7C9 is an ESD solution for the VGA or DVI-I port connector. This device integrates ESD protection for all signals, level shifting for the DDC signals and buffering for the SYNC signals. ESD protection for the VIDEO, DDC and SYNC lines is implemented with low-capacitance current steering diodes. Separate positive supply rails are provided for the VIDEO, DDC and SYNC channels to facilitate interfacing with low voltage video controller ICs to provide design flexibility in multi-supply-voltage environments. Two non-inverting drivers provide buffering for the HSYNC and VSYNC signals from the video controller IC (SYNC1, SYNC2).
