Philips Electronics 

Philips Semiconductors

PAL/NTSC colour processor for

PIP applications

Preliminary specification

TDA8310

FEATURES

• Multistandard vision IF circuit (positive and negative

modulation)

• Video switch which automatically detects whether the

incoming signal is CVBS or Y/C

• Integrated chrominance trap and bandpass filters

(automatically calibrated)

• Integrated luminance delay line

• Automatic PAL/NTSC decoder which can decode all

standards available in the world

• Easy interfacing with the TDA8395 (SECAM decoder)

for multistandard applications

• Horizontal PLL with an alignment-free horizontal

oscillator

• Vertical count-down circuit

• RGB/YUV and fast blanking switch with 3-state output

and active clamping

• Low dissipation (560 mW)

• Small amount of peripheral components compared with

competition ICs.

GENERAL DESCRIPTION

The TDA8310 is an alignment-free PAL/NTSC colour

processor for Picture-in-Picture (PIP) applications. The

circuit contains a vision IF amplifier, a PAL/NTSC colour

decoder, horizontal and vertical synchronization and an

RGB/YUV switch.

As input for the colour decoder and sync processor the

demodulated IF signal can be chosen but the circuit also

has a video input which automatically detects whether the

incoming signal is CVBS or Y/C. The output signals for the

PIP processor are:

Luminance signal

Colour difference signals (U and V)

Horizontal and vertical synchronization pulses.

The RGB/YUV switch can select between two RGB or

YUV sources, e.g. between the PIP processor and the

SCART input signal.

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

52-pin SDIP package.
