DESCRIPTION
CVBS1,
CVBS2,
CVBS3(Y)
7, 6, 5
I
75
Ω
Term,
1
μ
F AC-coupled
Composite Video Inputs. CVBS3(Y) is the Luminance (Y) signal in S-Video mode. These
inputs must each be terminated by a 75
Ω
resistor to AGND and AC-coupled by a 1.0μF
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
μ
F capacitor.
YOUT
9
O
External Anti-
Alias Filter
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.
YIN
8
I
Analog input to the ADC. See YOUT description above.
C

I
75
Ω
Term,

μ
F AC-coupled
and
External Anti-
Alias Filter
Chrominance (C) S-Video input. This input must each be terminated by a 75
Ω
resistor to
AGND and AC-coupled by a 1.0
μ
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
μ
F capacitor.
A/D TEST
17
O
none
Chroma signal A/D test pin. This pin must be left floating for proper operation.
RSET
28
O
12.1k
Ω
to AGND
A 12.1k
Ω
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.
REF_CAP
78
O
1.0μF
to AGND
Voltage reference capacitor. A 1μF ceramic capacitor must be connected between this pin
and AGND. This capacitor should be as close to this pin as possible for best performance.
