General Description

TDA4671 The TDA4671 delays the luminance signal and improves colour-difference signal transients.

The luminance signal can also be improved by peaking and noise reduction (coring).

Overview

INTEGRATED CIRCUITS DATA SHEET TDA4671 Picture Signal Improvement (PSI) circuit Product specification Supersedes data of June 1993 File under Integrated Circuits, IC02 1996 Dec 11 Philips Semiconductors Product.

Key Features

  • Luminance signal delay from 20 to 1100 ns (minimum step 45 ns).
  • Luminance signal peaking with symmetrical overshoots selectable.
  • Selectable 2.6 or 5 MHz peaking centre frequency and degree of peaking (.
  • 3, 0, +3 and +6 dB).
  • Selectable noise reduction by coring.
  • Handles negative as well as positive colour-difference signals.
  • Selectable Colour Transient Improvement (CTI) to decrease the colour-difference signal transient times to those.
