AN2526NFH
Automotive LCD TV signal processor IC
I
Overview
The AN2526NFH is a video signal processing IC with
an LCD's 5 V-source driving power supply for TFT color
LCD (normally white type), and it supports NTSC and
PAL 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.

Difference from the AN2526FH
Compared to the AN2526FH, the sync. system gain is
increased in no signal input. This may cause the picture
on the screen to be swaying horizontally. So we cannot
recommend this IC to be used in the set with no-signal
input mode.
