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.
