WT8876S
The WT8876S is a highly integrated video display controller for medium and small size LCD display applications, such as car TV (connect to Car PC), and other applications with R/G/B input. It has built-in 3-channel video ADC, video decoder, scaler, de-interlacer, TCON, 8-bit MCU, OSD, PWM, and DC-to-DC converter functions. WT8876S has 18-bit and 24-bit digital RGB output interface and LVDS output for digital LCD panel application.
