DESCRIPTION
Aux Chroma Output: This output provides a chroma signal to the auxiliary SCART
connector to support SVHS operation. This pin is typically AC coupled to pin 15 of the
auxiliary SCART connector. When the S-video mode is selected, a chroma signal from
the video encoder is output to this pin.
TV Modulator Video Output: This pin provides composite video for an external RF
modulator. The signal on this pin follows the composite video output to the TV_YCout
pin.
TV Video Output: This pin is the composite video output to the TV SCART connector
(pin 19). In the SVHS mode, this pin provides luminance information.
TV Red Output: This pin provides Red video to the TV SCART connector (pin 15). In
SVHS mode, this pin provides the chroma information.
TV Green Output: This pin provides Green video to the TV SCART connector (pin 11).
TV Blue Output: This pin provides Blue video to the TV SCART connector (pin 7).
TV Left Audio Output: This pin is the output to the left channel audio (pin 3) of the TV
SCART connector.
TV Right Audio Output: This pin is the output to the right channel audio (pin1) of the TV
SCART connector.
TV Function Pin: This is a bi-directional pin. As an input, it digitizes the analog voltage
on the TV SCART function pin. As an output, it puts out one of three voltage levels to
the TV SCART function pin.
Digital Output 0: This pin is a general purpose output that is controlled by serial port
register.
Digital Output 1: This pin is a general purpose output that is controlled by serial port
register.
Serial Clock Input: This pin accepts a serial port clock input signal.
Serial Data Input/Output that can receive or transmit serial data.
+5 VDC power supply pins.
-5 VDC power supply pins.
+12 VDC power supply pin for function switching circuits.
Internal voltage reference, bypass pin. Add capacitor 0.1 uF( 1.0 uF for better PSRR ) to
ground.
Ground for all blocks.
Bias point of internal current generator. Add resistor 10.0k( + 1% ) to ground.
Reference point for internal timing circuit. Add capacitor 470 pF to ground.
