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.
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.
