Description
X
PRESS
O-TC is a breakthrough in configurable
Frequency Control Solutions. X
PRESS
O-TC
utilizes a family of proprietary ASICs, designed
and developed by Fox, with a key focus on noise
reduction technologies and tight temperature
stability.
The 3
rd
order Delta Sigma Modulator reduces
noise to the levels that are comparable to
traditional Bulk Quartz and SAW oscillators.
With short lead-time, low cost, low noise, wide
frequency range, and excellent temperature
performance, X
PRESS
O-TC is an ideal choice
over the conventional technologies.
Finished X
PRESS
O-TC parts are 100% final
tested.
