Composite Video Inputs. CVBS3(Y) is the Luminance (Y) signal in S-Video mode. These
inputs must each be terminated by a 75 resistor to AGND and AC-coupled by a 1.0 F
capacitor as shown in the Reference Schematic. These components should be as close to
this pin as possible for best performance. If not used, this pin should be connected to AGND
through a 0.1 F capacitor.
Analog output of the video multiplexer. A external low-pass anti-alias filter between the
YOUT and YIN pins, as shown in the Reference Schematic. The filter components should
be as close as possible to the YOUT and YIN pins for best performance.
Analog input to the ADC. See YOUT description above.
Chrominance (C) S-Video input. This input must each be terminated by a 75 resistor to
AGND and AC-coupled by a 1.0 F capacitor as shown in the Reference Schematic. These
components, and the corresponding anti-alias low-pass filter, should be as close to this pin
as possible for best performance. If not used, this pin should be connected to AGND
through a 0.1 F capacitor.
Chroma signal A/D test pin. This pin must be left floating for proper operation.
A 12.1K resistor must be connected between this pin and AGND. This resistor should be
as close to this pin as possible for best performance. The function of this pin has changed
from the HMP8112A/15 GAIN_CNTRL input. Do not use capacitor decoupling for this output
pin.
Voltage reference capacitor. A 1 F ceramic capacitor must be connected between this pin
and AGND. This capacitor should be as close to this pin as possible for best performance.
