AN2546FH-A
Automotive LCD TV signal processor IC
■ 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 sig-
nal processing circuit, interface circuit, synchronizing cir-
cuit and many color quality adjusting circuits. This IC con-
verts the composite video signal or separated Y/C signal
or RGB signals into RGB signals available for TFT color
LCD.
■ 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 sys-
tems
• Supporting composite, component and color differen-
tial signal input
• Video signal, analog RGB (2 systems)
One is for OSD (analog/digital).
• Each mode setting is possible with I
2
C Bus control.
• Electronic volume (D/A converter) built in
• Contrast/Brightness/γ correction circuit built in
• Horizontal and vertical display position adjustment are
possible by serial control.
• Improvement of weak electric field characteristics
(Compared to AN2526FH/AN2526NFH: −5 dB)
• At reverse stop, built-in output gain down function
■ Applications
• 4 inches to 7 inches middle size TFT LCD equipment
of normally white, of such as an in-car TV and an LCD
monitor for car navigation system.
