Pin Name
The R, G, and B image signals are input using
these pins.
Provides the power for the digital circuits.
Image data input pins.
Analog image signal output pins.
Internal shift register start pulse input and
output pins.
Input signal that selects the shift direction.
High: Right shift (Y1 to Y384)
Low: Left shift (Y384 to Y1)
Data acquisition clock input pin.
Controls the analog voltage output.
Switches the reference voltage for odd and even
outputs.
Controls inversion of the input image signal.
INV1: Used for D2(7 : 0), D1(7 : 0), D0(7 : 0)
INV2: Used for D5(7 : 0), D4(7 : 0), D3(7 : 0)
Inputs the correction voltage used by the D/A
converter.
Provides the reference voltage that determines
the analog circuit operating point.
VOPU: Reference voltage for the high side output
VOPL : Reference voltage for the low side output
Used for device testing.
This pin must be left open during normal operation.
