TDA4657 - Generic multi-standard decoder

General Description

The TDA4657 is a monolithic integrated multi-standard colour decoder for PAL, SECAM and NTSC 4.43 MHz with negative colour difference output signals.

It is adapted to the integrated baseband delay line TDA4660/61.

MIN.

Key Features

  • Low voltage (8 V).
  • Low power dissipation (250 mW).
  • Automatic standard recognition.
  • No adjustments required.
  • Reduced external components.
  • Not all time constants integrated (ACC, SECAM de-emphasis). QUICK.
