PAL decoder TDA4510

GENERAL DESCRIPTION

The TDA4510 is a colour decoder for the PAL standard, which is pin sequent compatible with multistandard decoder
TDA4555 and also pin compatible with NTSC decoder TDA4570. It incorporates the following functions:

Chrominance part

• Gain controlled chrominance amplifier with operating point control stage

• Chrominance output stage for driving the 64 µs delay line

• Blanking circuit for the colour burst signal

• Automatic chrominance control (ACC) with sampled rectifier during burst-key

Oscillator and control voltage part

• Reference oscillator for double subcarrier frequency

• Gated phase comparison

• Identification demodulator and automatic colour killer

• Sandcastle pulse detector

• Service switch

Demodulator part

• Two synchronous demodulators for the (B-Y) and (R-Y) signals

• PAL flip-flop and PAL switch

• Colour switching stages

• Separate colour switching output

• (B-Y) and (R-Y) signal output stages

• Internal filtering of residual carrier
