TDA4671 - Picture Signal Improvement PSI

Description

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).

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.
