between RSET and ground. No other connections should be made to
this pin.
Luminance Output
A 75
between Y and ground for optimum performance. In normal operating
modes other than SCART and RGB bypass, this pin outputs the
composite video signal. In SCART and RGB Bypass modes, this pin
outputs the red signal.
Chrominance Output
A 75
between C and ground for optimum performance. In normal operating
modes other than SCART and RGB bypass, this pin outputs the
composite video signal. In SCART and RGB Bypass modes, this pin
outputs the green signal.
Composite Video Output
A 75
between CVBS and ground for optimum performance. In normal
operating modes other than SCART and RGB bypass, this pin outputs
the composite video signal. In SCART and RGB Bypass modes, this pin
outputs the blue signal.
Composite Sync Output
A 75
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 I
I
and is not 5V tolerant.
Serial Clock (Internal pull-up)
This pin functions as the serial clock pin of the I
the I
supply and is not 5V tolerant.
Reset Input
When this pin is low, the CH7006 is held in the power-on reset
condition. When this pin is high, the device operates normally and
reset is controlled through the I
Analog ground
This pin provides the ground reference for the analog section of the
CH7006, and MUST be connected to the system ground, to prevent
latchup. Refer to the Application Information section for information on
proper supply decoupling.
Analog Supply Voltage
This pins supplies the 5V power to the analog section of the CH7006.
DAC Power Supply
This pins supplies the 5V power to CH7006’s internal DAC’s.
