Panasonic AN5337K Datasheet

ICs for TV

■ Overview

The AN5337K is suitable for processing of video, chroma, RGB, synchronization, and deflection signals of NTSC system. It incorporates an I2C bus controller.

■ Features

•

Video : Wide bandwidth filter, adjustable preshoot and

overshoot, adjustable aperture control, ABL input

•

Chroma : ACC filter, color difference output

•

RGB : Color difference input, RGB output

•

Synchronization : Synchronous BLK input/output,

adjustable AFC1 time-constant, adjustable horizontal

center

•

Deflection : Generation of parabola waves and saw-

tooth waves, distortion correction
