TDA4556 Datasheet Multistandard Decoder

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS DATA SHEET TDA4555 TDA4556 Multistandard decoder Product specification File under Integrated Circuits, IC02 November 1984 Philips Semiconductors Product specification Multistandard.

General Description

The TDA4555 and TDA4556 are monolithic integrated multistandard colour decoders for the PAL, SECAM, NTSC 3,58 MHz and NTSC 4,43 MHz standards.

The difference between the TDA4555 and TDA4556 is the polarity of the colour difference output signals (B-Y) and (R-Y).

Key Features

  • Chrominance part.
  • Gain controlled chrominance amplifier for PAL, SECAM and NTSC.
