The AN2546FH-A is a video signal processing IC built-in a 5-volt power-supply source driver for TFT color LCD (normally white type), and it supports the NTSC, PAL and PAL-M/PAL-N systems. The main circuitry of this IC includes video-signal processing circuit, color signal processing circuit, interface circuit, synchronizing circuit and many color quality adjusting circuits. This IC converts the composite video signal or separated Y/C signal or RGB signals into RGB signals available for TFT color LCD.
