NOTES:
1. Color subcarrier input [FSC = (455/2) fh] locked on the burst signal of the input video signal. AC coupling input by external capacitor.
2. The internal circuit operates by 4 times clock using FSC pin input at normal (FSC) mode.
The internal circuit operates by FSC pin input clock at expected normal (FSC) mode.
3. Sine wave input.
4. CLK(AD) is available only during digital input comb filter mode.
This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, precau-
tions must be taken to avoid applications of any
voltage higher than maximum rated voltages to
this high–impedance circuit. For proper opera-
tion, Vin and Vout should be constrained to the
range GND
≤
(Vin or Vout)
≤
VCC.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either
GND or VCC). Unused outputs must be left
open.
