processor

Objective specification

TDA8366

FEATURES

• Multistandard vision IF circuit (positive and

negative modulation)

• Video identification circuit in the IF circuit which is

independent of the synchronization for stable On Screen

Display (OSD) under ‘no-signal’ conditions

• Source selection with 2 Colour Video Blanking

Synchronization (CVBS) inputs and a Y/C (or extra

CVBS) input

• Output signals of the video switch circuit for the teletext

decoder and a Picture-In-Picture (PIP) processor

• Integrated chrominance trap and bandpass filters

(automatically calibrated)

• Integrated luminance delay line

• Asymmetrical peaking in the luminance channel with a

(defeatable) noise coring function

• PAL/NTSC colour decoder with automatic search

system

• Easy interfacing with the TDA8395 (SECAM decoder)

for multistandard applications

• RGB control circuit with black-current stabilization and

white point adjustment; to obtain a good grey scale

tracking the black-current ratio of the 3 guns depends on

the white point adjustment

• Linear RGB inputs and fast blanking

• Horizontal synchronization with two control loops and

alignment-free horizontal oscillator

• Vertical count-down circuit

• Geometry correction by means of modulation of the

vertical and EW drive

• I2C-bus control of various functions

• Low dissipation (850 mW)

• Small amount of peripheral components compared with

competition ICs

• Only one adjustment (vision IF demodulator)

• Y, U and V inputs and outputs.

GENERAL DESCRIPTION

The TDA8366 is an I2C-bus controlled PAL/NTSC TV

processor. The circuit has been designed for use with the

baseband chrominance delay line TDA4665 and for

DC-coupled vertical and East-West (EW) output stages.

The device can process both CVBS and Y/C input signals

and has a linear RGB-input with fast blanking.

The peaking circuit generates asymmetrical overshoots

(the amplitude of the ‘black’ overshoots is approximately

2 times higher as the one of the ‘white’ overshoots) and

contains a (defeatable) coring function.

The RGB control circuit contains a black-current stabilizer

circuit with internal clamp capacitors. The white point of the

picture tube is adjusted via the I2C-bus.

The deflection control circuit provides a drive pulse for the

horizontal output stage, a differential sawtooth current for

the vertical output stage and an East-West drive current for

the East-West output stage.These signals can be

manipulated for geometry correction of the picture.

The supply voltage for the IC is 8 V. The IC is available in

an SDIP package with 52 pins and in a QFP package with

64 pins (see Chapter “Ordering information”).

The pin numbers indicated in this document are

referenced to the SDIP52; SOT247-1 package; unless

otherwise indicated.
