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
