Product Summary

The TDA4780 is a monolithic integrated circuit with a luminance and a colour difference interface for video processing in TV receivers. The primary function of the TDA4780 is to process the luminance and colour difference signals from a colour decoder.

Parametrics

TDA4780 absolute maximum rating: (1)VP supply voltage: -0.1 +9.0 V; (2)V10, 11, 12 (RGB)1 inputs: -0.1 VP V; (3)V2, 3, 4 (RGB)2 inputs: -0.1 VP V; (4)V8, 7, 6 Y, CD-input:s -0.1 VP V; (5)V13, 1 switch 1 and switch 2 input voltage: -0.1 VP V; (6)V25, 23, 21, 17 black level, leakage storage: -0.1 VP V; (7)V14 sandcastle: -0.7 VP + 5.8 V; (8)V15 average current information: -0.7 VP + 0.7 V; (9)V16 peak drive storage: -0.1 VP V; (10)V18 peak dark storage: -0.1 VP V; (11)V19 cut-off control input voltage: -0.7 VP + 0.7 V; (12)V27, 28 I2C-bus: SDA and SCL voltage: -0.1 VP V.

Features

TDA4780 features: (1)Gamma adjust; (2)Dynamic black control (adaptive black); (3)All input signals clamped on black-levels; (4)Automatic cut-off control, alternative: output clamping on fixed levels; (5)Three adjustable reference voltage levels via I2C-bus for automatic cut-off control; (6)Luminance/colour difference interface; (7)Two luminance input levels allowed; (8)Two RGB interfaces controlled by either fast switches or by I2C-bus; (9)Two peak drive limiters, selection via I2C-bus; (10)Blue stretch, selection via I2C-bus; (11)Luminance output for scan velocity modulation (SCAVEM); (12)Extra luminance output; same pin can be used as hue control output; (13)Non standard operations like 50 Hz/32 kHz are also possible; (14)Either 2 or 3 level sandcastle pulse applicable; (15)High bandwidth for 32 kHz application; (16)White point adjusts via I2C-bus.
