FEATURES
● Luminance signal delay from 20 to 1100 ns (minimum step 45 ns)● Luminance signal peaking with selectable symmetrical overshoots
● 2.6 or 5 MHz peaking centre frequency and selectable degree of peaking (−3, 0, +3 and +6 dB)
● Selectable noise reduction by coring
● Handles negative and 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 components required. QUICK REFERENCE DATA SYMBOL VP IP(tot) td(Y) Vi(VBS) Vi(CD)(p-p) total supply current Y signal delay time...
