AN2546FH-A

ICs for TV AN2546FH-A Automotive LCD TV signal processor IC I Overview 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. 12.00±0.20 10.00±0.20 48 49 33 32 Unit: mm 64 1 0.50 16 17 (1.25) I Features Supply voltage: 3 V/5 V/7.5 V Built-in a 5-volt power-supply source driver for TFT type LCD Low consumption power (typ. 200 mW) Supporting the NTSC, PAL, PAL-M and PAL-N Supporting composite, component and color differential signal input Video signal analog RGB (2 systems) One is for OSD (analog/digital). Each mode setting is possible with I2C Bus control.
