Power-Supply Bypassing

and Ground Management

The MAX9532 operates from a 3V to 3.6V single supply

and requires proper layout and bypassing. For the best

performance, place the components as close as possi-

ble to the device.

Proper grounding improves performance and prevents

any switching noise from coupling into the video signal.

Bypass the analog supply (VDD) with a 1µF capacitor to

GND, placed as close as possible to the device.

Bypass CPVSS to GND with a 1µF ceramic capacitor in

parallel with a 10nF low-ESR capacitor. The bypass

capacitors should be placed as close as possible to

the device.
