Board Layout Considerations and

Bypassing

The MAX9491’s high-frequency oscillator requires

proper layout to ensure stability. For best performance,

place components as close as possible to the device.

Digital or AC transient signals on GND can create noise

at the clock output. Return GND to the highest quality

ground available. Bypass each V

and V

DDA

with a

0.1µF capacitor, placed as close as possible to the

device. Careful PC board ground layout minimizes

crosstalk between the output and digital inputs.
