I

Shift direction selection

signal input

Input signal that selects the shift direction.

High: Right shift (Y1 to Y384)

Low: Left shift (Y384 to Y1)

I

Clock input

Data acquisition clock input pin.

I

Analog output control

Controls the analog voltage output.

I

Output polarity reversal

control input

Switches the reference voltage for odd and even

outputs.

I

Data inversion control input 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)

I

γ correction voltage input

Inputs the γ correction voltage used by the D/A

converter.

I

Analog reference voltage

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

I

Analog system power supply Provides the power for the analog circuits.

I

Digital system power supply Provides the power for the digital circuits.

I

Test

Used for device testing.

(Pull-down resistor: 100 kΩ) This pin must be left open during normal operation.
