INTEGRATED CIRCUITS DATA SHEET TDA4510 PAL decoder Product specification File under Integrated Circuits, IC02 March 1986 Philips Semiconductors Product specification PAL decoder GENERAL DESCRIPTION TDA4510 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 QUICK REFERENCE DATA Supply voltage Supply current Chrominance input signal (peak-to-peak) Chrominance output signal (peak-to-peak) Colour difference output signals (peak-to-peak values) -(R-Y) signal -(B-Y) signal Sandcastle pulse, required amplitude for burst gating level horizontal pulse separation vertical and horizontal pulse separation PACKAGE OUTLINE 16-lead DIL; plastic (SOT38); SOT38-1; 1996 November 26.

Philips Semiconductors Product specification PAL decoder FUNCTIONAL DESCRIPTION DIVIDER STAGES TDA4510 The divider stages provide -(R-Y) and -(B-Y) reference signals with the correct 90 degrees relation for the demodulators. PHASE COMPARATOR The phase comparator compares the -(R-Y) reference signal with the burst pulse and controls the frequency and phase of the reference oscillator. IDENTIFICATION DEMODULATOR The identification demodulator delivers a positive going identification signal for PAL-signals at pin 14, also used for the automatic colour-killer. SERVICE SWITCH The service switch has two functions. The first position (V14-3 < 1 V) allows the adjustment of the reference oscillator. Therefore the colour is switched on and the burst for the oscillator PLL is switched off. The second position (V14-3 > 5 V) switches the colour on and the output signals can be observed.
