TDA8501 - PAL/NTSC encoder

General Description

TDA8501 The TDA8501 is a highly integrated PAL/NTSC encoder IC which is designed for use in all applications where R, G and B or Y, U and V signals require transformation to PAL or NTSC values.The specification of the input signals are fully compatible with the specification of those of the TDA850

Key Features

  • Two input stages: R, G, B and.
  • (R.
  • Y),.
  • (B.
  • Y), Y with multiplexing.
  • Chrominance processing, highly integrated, includes low frequency filters for the colour difference signals, and after the modulator a bandpass filter.
  • Fully controlled modulator produces a signal according to the PAL or NTSC standard without adjustments.
  • A free running oscillator. Can be tuned by crystal or by an external frequency source.
  • Output stage.

INTEGRATED CIRCUITS DATA SHEET TDA8501 PAL/NTSC encoder Preliminary specification File under Integrated Circuits, IC02 April 1993 Philips Semiconductors Preliminary specification PAL/NTSC encoder FEATURES • Two input stages: R, G, B and −(R−Y), −(B−Y), Y with multiplexing • Chrominance processing, highly integrated, includes low frequency filters for the colour difference signals, and after the modulator a bandpass filter • Fully controlled modulator produces a signal according to the PAL or NTSC standard without adjustments • A free running oscillator. Can be tuned by crystal or by an external frequency source • Output stages with separated Y + SYNC and chrominance (Y + C, SVHS), and a CVBS output. Signal amplitudes are correct for 75 Ω driving via an external emitter follower.
