Description

plastic dual in-line package; 28 leads (600 mil) plastic leaded chip carrier; 28 leads GENERAL DESCRIPTION TDA4681 The TDA4681 is a monolithic integrated circuit with a colour difference interface for video processing in TV receivers.Its primary function is to process the luminance and colour difference signals from multistandard colour decoders, TDA4555, TDA4650/T, TDA4655/T or TDA4657, Colour Transient Improvement (CTI) IC, TDA4565, Picture Signal Improvement (PSI) IC, TDA4670 or from a fea

Features

Operates from an 8 V DC supply.
Black level clamping of the colour difference, luminance and RGB input signals with coupling-capacitor DC level storage.
Two fully-controlled, analog RGB inputs, selected either by fast switch signals or via I2C-bus.
Saturation, contrast and brightness adjustment via I2C-bus.
Same RGB output black levels for Y/CD and RGB input signals.
Timing pulse generation from either a 2 or 3-level sandcastle pulse for cla.
