Description
The M52042FP is a semiconductor integrated circuit (IC) for picture signal processing that has been developed for
NTSC system LCD color TV.
This IC has a built-in luminance signal processing circuit and color signal processing circuit, which is employed to
convert a composite video signal to an RGB signal.
Features
Low voltage and low power dissipation design
Built-in Y/C separation circuit and external chroma trap switchable (fc is nearly equal to 1.5 MHz.)
Built-in sync separation circuit
Provided with Y-signal blanking function by HD pulse
R.G.B. signal output
Tint, contrast, picture quality and color control linearly adjustable
24-pin, shrink pitch, flat package employed
Same package as in PAL system video chroma IC M52045FP, pin perfectly compatible
Application
LCD color TV and LCD color view finder
Recommended Operating Condition
Supply voltage range: 3.7 to 4.5 V
Rated supply voltage: 4.0 V
