Summary
TC90193ASBG
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC90193ASBG
Video signal processing IC for small LCD
1. Overview
TC90193ASBG is a video processing IC for small LCD panel
(QVGA to WVGA).
It corresponds to the input of an analog CVBS
signal and digital RGB signal.
It performs video(picture) processing to the selected input
signal, and outputs the digital RGB picture signal and panel
control signal of QVGA-WVGA.
