TDA8361 - Integrated PAL and PAL/NTSC TV processors - NXP Semiconductors

Philips Semiconductors Objective specification

Integrated PAL and PAL/NTSC TV

processors

TDA8360; TDA8361; TDA8362

FEATURES

Available in TDA8360, TDA8361

and TDA8362

· Vision IF amplifier with high

sensitivity and good differential

gain and phase

· Multistandard FM sound

demodulator (4.5 MHz to 6.5 MHz)

· Integrated chrominance trap and

bandpass filters (automatically

calibrated)

· Integrated luminance delay line

· RGB control circuit with linear RGB

inputs and fast blanking

· Horizontal synchronization with two

control loops and alignment-free

horizontal oscillator without

external components

· Vertical count-down circuit

(50/60 Hz) and vertical preamplifier

· Low dissipation (700 mW)

· Small amount of peripheral

components compared with

competition ICs

· Only one adjustment (vision IF

demodulator)

· The supply voltage for the ICs is

8 V. They are mounted in a shrink

DIL envelope with 52 pins and are

pin compatible.

Additional features

TDA8360

· Alignment-free PAL colour decoder

for all PAL standards, including

PAL-N and PAL-M.

TDA8361

· PAL/NTSC colour decoder with

automatic search system

· Source selection for external

audio/video (A/V) inputs (separate

Y/C signals can also be applied).

TDA8362

· Multistandard vision IF circuit

(positive and negative modulation)

· PAL/NTSC colour decoder with

automatic search system

· Source selection for external

A/V inputs (separate Y/C signals

can also be applied)

· Easy interfacing with the TDA8395

(SECAM decoder) for

multistandard applications.

GENERAL DESCRIPTION

The TDA8360, TDA8361 and

TDA8362 are single-chip TV

processors which contain nearly all

small signal functions that are

required for a colour television

receiver. For a complete receiver the

following circuits need to be added:

a base-band delay line (TDA4661),

a tuner and output stages for audio,

video and horizontal and vertical

deflection.

Because of the different functional

contents of the ICs the set maker can

make the optimum choice depending

on the requirements for the receiver.

The TDA8360 is intended for simple

PAL receivers (all PAL standards,

including PAL-N and PAL-M are

possible).

The TDA8361 contains a PAL/NTSC

decoder and has an A/V switch.

For real multistandard applications

the TDA8362 is available. In addition

to the extra functions which are

available in the TDA8361, the

TDA8362 can handle signals with

positive modulation and it supplies

the signals which are required for the

SECAM decoder TDA8395.
