General Description

TDA4672 The TDA4672 delays the luminance signal.

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

MAX.

Key Features

  • Luminance signal delay from 20 ns to 1100 ns (minimum step 45 ns).
  • Selectable luminance signal peaking with symmetrical overshoots.
  • Selectable 2.6 or 5 MHz peaking centre frequency and degree of peaking from.
  • 6 dB to +9 dB in 16 steps of 1 dB each.
  • Selectable noise reduction by coring.
  • Selectable 5 or 12 V sandcastle input voltage.
  • All controls selected via the I2C-bus.
  • Timing pulse generation for clamping and delay time con.
