Description

The Fox X

PRESS

O Crystal Oscillator is a

breakthrough in configurable Frequency Control

Solutions. X

PRESS

O utilizes a family of

proprietary ASICs, designed and developed by

Fox, with a key focus on noise reduction

technologies.

The 3

rd

order Delta Sigma Modulator reduces

noise to the levels that are comparable to

traditional Bulk Quartz and SAW oscillators.

The ASICs family has ability to select the output

type, input voltages, and temperature

performance features.

With the X

PRESS

lead-time, low cost, low noise,

wide frequency range, excellent ambient

performance, XpressO is an excellent choice

over the conventional technologies.

Finished X

PRESS

O parts are 100% final tested.
