GENERAL DESCRIPTION
The TDA4672 delays the luminance signal. The luminance signal can also be improved by peaking and noise reduction (coring).

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 control synchronized by sandcastle pulse
• Automatic luminance signal delay correction using a control loop
• Luminance input signal clamping with coupling capacitor
• 4.5 to +8.8 V supply voltage
• Minimum of external components.
