In
RSET
Reference Resistor
A 360
resistor with short and wide traces should be attached
between RSET and ground. No other connections should be made to
this pin.
Luminance Output
A 75
termination resistor with short traces should be attached
between Y and ground for optimum performance.
In normal operating
modes other than SCART, this pin outputs the luma video signal. In
SCART mode, this pin outputs the red signal.

Chrominance Output
A 75
termination resistor with short traces should be attached
between C and ground for optimum performance.
In normal operating
modes other than SCART, this pin outputs the chroma video signal. In
SCART mode, this pin outputs the green signal.
Composite Video Outpu
t
A 75
termination resistor with short traces should be attached
between CVBS and ground for optimum performance. In normal
operating modes other than SCART, this pin outputs the composite
video signal. In SCART mode, this pin outputs the blue signal.

CSYNC
Composite Sync Output
A 75
termination resistor with short traces should be attached
between CSYNC and ground for optimum performance. In SCART
mode, this pin outputs the composite sync signal.
Serial Data (External pull-up required)
This pin functions as the serial data pin of the serial interface port (see
the
serial Port Operation
section for details).
Serial Clock (Internal pull-up)
This pin functions as the serial clock pin of the serial interface port (see
the
serial Port Operation
section for details).

ADDR
Serial Address Select (Internal pull-up)
This pin is the serial Address Select, which corresponds to bits 1 and 0
of the serial device address (see the
serial Port Operation
section for
details), creating an address selection as follows:
ADDR Serial Address Selected
1 11101

= 75H = 117
0 11101

= 76H = 118
Analog ground
These pins provide the ground reference for the analog section of the
CH7013A, and MUST be connected to the system ground, to prevent
latchup. Refer to the
Application Information
section for information on
proper supply de-coupling.
Analog Supply Voltage
These pins supply the 5V power to the analog section of the CH7013A.
