Solutions. X
PRESS
O-ULTR utilizes a family of
RA
f
proprietary ASICs, designed and developed by Fox,
A
with a key foc on noise reduction tec
cus
chnologies.
The 4
th
order Delta Sigma Modulator re
r
educes noise to
the levels tha are compar
at
rable to traditi
ional Bulk
Quartz and SAW oscillators. The ASIC family has
S
Cs
the ability to select the out
s
tput type and supply
voltage.
With the X
