TDA4651 Overview
TDA4651 The TDA4651 is a monolithic integrated multistandard colour decoder for PAL, SECAM and NTSC (3.58 and 4.43 MHz) with negative colour difference output signals. The colour difference output signals are fed to the TDA4661, switched capacitor delay line.

TDA4651 Key Features
- Gain controlled chrominance amplifier
- ACC demodulation controlled by system scanning
- Internal colour difference signal output filters to remove the residual subcarrier
- PAL / NTSC demodulation
- H (burst) and V blanking
- PAL switch (disabled for NTSC)
- NTSC phase shift (disabled for PAL)
- PLL-controlled reference oscillator
- two reference oscillator crystals on separate pins with automatic switching
- quadrature demodulator with subcarrier reference
