Notes on Operation
1. Signal input timings to the timing generator
Input Signal Timing Chart
Maintain the relationship in the timing chart. While PRG is high, video input signal must not be changed.
The same name output from Sony's LCD timing generators CXD2442Q and CXD2453Q satisfy the above
conditions.
If the above timing does not be satisfied, timing violation may cause decay of characteristics or IC damage in
some case. Especially do not input FRP pulse without ENB and PRG input.
We strongly recommend to verify the design on this timings and presence of ENB and PRG.
2. Notes on Mounting
• Please be sure that the wiring for internal timing generator link pins NEXT_IN (Pin 4) and NEXT_OUT (Pin 3)
• The eight pins 8, 9, 24, 25, 40, 41, 56 and 57 are connected to the "die pad" inside the package. A good
• Be sure to short PVcc (Pin 26) and Vcc (Pin 43) so that they go on and off simultaneously.
3. Input Video Signal
• Please be sure that the video signal amplitude (0% black level to 100% white level) which inputs to sample

is as short as possible, in especially 12-outputs. Also, do not locate a large amplitude high-speed signal path
(such as CMOS logic) near the wiring.
thermal radiation effect can be achieved by a thick connection to GND plane.

Also, as for inputting to sample and hold, do not apply DC level of 2V or lower during operation.
