TDA4671
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 d B)
- 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 high frequency luminance signals
- 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 and colour-difference input signal clamping with coupling capacitor
- 4.5 to 8.8 V supply voltage range
- Minimum of external ponents. QUICK REFERENCE DATA SYMBOL VP IP(tot) td(Y) Vi(VBS)(p-p) Vi(CD)(p-p) PARAMETER supply voltage (pins 1 and 5)...
