PAL/NTSC colour processor for PIP applications
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
TDA8310A
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.
