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 Output
A 75
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.
Composite Sync Output
A 75
CSYNC and ground for optimum performance. In SCART mode, this pin
outputs the composite sync signal.
Serial Data (External pull-up required)
This pin functins as SD, the serial data pin of the serial port interface (see
the Serial Port Operation section for details).
Serial Clock (Internal pull-up)
This pin functions as the serial clock pin of the serial port interface (see the
Serial Port Operation section for details).
Serial Port Address Select (Internal pull-up)
This pin is the Serial Port Address Select, which corresponds to bits 1 and 0
of the serial port device address (see the I
details), creating an address selection as follows:
Analog ground
These pins provide the ground reference for the analog section of CH7003,
and MUST be connected to the system ground, to prevent latchup.
Analog Supply Voltage
These pins supply the 5V power to the analog section of the CH7003.
DAC Power Supply
These pins supply the 5V power to CH7003’s internal DACs.
DAC Ground
These pins provide the ground reference for CH7003’s internal DACs.
Digital Supply Voltage
These pins supply the 3.3V power to the digital section of CH7003.
Digital Ground
These pins provide the ground reference for the digital section of CH7003,
and MUST be connected to the system ground to prevent latchup.
R (Red) Component Output
This pin provides the analog Red component of the digital RGB input in the
RGB Pass-Through mode.
G (Green) Component Output
This pin provides the analog Green component of the digital RGB input in
the RGB Pass-Through mode.
B (Blue) Component Output
This pin provides the analog Blue component of the digital RGB input in the
RGB Pass-Though mode.
