Function
VSSA
VCO
Analog Ground.
Used for internal analog circuitry.
Voltage Control Oscillator.
Used to control the internal oscillator
frequency by DC voltage input from an external low pass filter.
Bias Resistor.
Used to regulate the appropriate bias current for the
internal oscillator to resonate at a specific dot frequency.
Analog Power Supply.
Positive 5 V DC supplies for internal analog
circuitry. A 0.1uF decoupling capacitor should be connected across
VDDA and VSSA.
Horizontal Input.
Used to input the horizontal synchronizing signal. It is
negative edge triggered and has an internal 100 k
pull-up resistor.
Serial Interface Enable.
Used to enable the serial data and to select I
2
C
or SPI bus operation. If this pin is left floating, the I
2
C bus is enabled,
otherwise the SPI bus is enabled.
Serial Data Input.
Transfers data through this pin to the internal display
and control registers. It has an internal 100 k
pull-up resistor.
Serial Clock Input.
Used to synchronize the data transfer. It has an
internal 100 k
pull-up resistor.
Digital Power Supply.
Positive 5 V DC supply for internal digital
circuitry and a 0.1uF decoupling capacitor should be connected across
VDD and VSS.
Vertical Input.
Used to input the vertical synchronizing signal. It is
negative triggered and has an internal pull-up resistor.
Half Tone Output.
Used to attenuate the external R, G, B amplifiers
gain for the transparent windowing effect.
Fast Blanking Output.
Used to cut off the external R, G, B signals
while this chip is displaying characters or windows.
Blue Color Output.
A blue color video signal output.
Green color output.
It is a green color video signal output.
Red Color Output.
A red color video signal output.
Digital Ground.
Used for internal digital circuitry.
