Description

Input the 100% white level DC of the

signal input to VIDEO_I.

When using the CXA2111R,

connect to the V33 output of the

CXA2111R. When using bipolar

DAC output for VIDEO_I, connect to

the DAC supply voltage.

Video input.

Connect a gamma-corrected

1.5Vp-p analog video output.

Can be connected directly to the

CXA2111R video output. Connect

to 5V when not using the invert

amplifier.

Calibration amplifier output.

Connect directly to Pin 51.

When using two CXA3512R in

parallel in XGA or UXGA mode, use

the calibration amplifier of only one

IC, and connect the output to Pin 51

of both ICs.

Dot clock inputs.

PECL differential input or TTL input.

For TTL input, input to MCLK and

connect MCLKX to GND via a

capacitor.

Always input the dot clock or

100µ equivalent signal to these pins even

when not using CLKOUT.

(Otherwise, noise may result.)
