Philips Semiconductors
PAL/NTSC colour processor
for PIP applications
Product specification
TDA8310A
FEATURES
• Video switch with 2 CVBS inputs. One input can be
switched between CVBS and Y/C and the circuit can
automatically detect 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 TDA8310A is an alignment-free PAL/NTSC colour
processor for Picture-in-Picture (PIP) applications.
The main difference between the TDA8310 and the
TDA8310A is that the vision IF amplifier has been omitted
in the TDA8310A. Therefore, the circuit contains an input
signal selector, a PAL/NTSC colour decoder, horizontal
and vertical synchronization and an RGB/YUV switch.
The input signal selector has 2 CVBS inputs. One of the
inputs can be switched between CVBS and Y/C and the
circuit can automatically detect 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.
