TDA4650 Description

Short technical summary and product information.

The TDA4650 by NXP Semiconductors is a versatile, monolithic integrated circuit designed for multistandard colour decoding. It supports PAL, SECAM, and NTSC (3.58 and 4.43 MHz) television standards, outputting negative colour difference signals.

Key features include automatic standard identification, allowing for seamless switching between broadcast formats. The device incorporates a PLL-controlled reference oscillator and quadrature demodulators for accurate signal processing. It also features gain-controlled chrominance amplification and internal colour-difference signal output filters to minimize residual subcarrier.

Available in 28-pin DIP (Through Hole) and 28-pin PLCC (Surface Mount) packages, the TDA4650 is suitable for various video processing applications. Its design facilitates integration with switched capacitor delay lines like the TDA4660/TDA4661.

Electrical specifications include a typical supply voltage of 12V and a supply current of 60mA. Input chrominance voltage ranges from 20mV to 400mV peak-to-peak, with output colour-difference voltages varying based on the standard and output pin.
