TDA4671 Overview
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).

TDA4671 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 of the h
- Selectable 5 or 12 V sandcastle input voltage
- All controls selected via the I2C-bus
- Timing pulse generation for clamping and delay time control synchronized by sandcastle pulse
- Automatic luminance signal delay correction using a control loop
