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.

STEP #1:
Customer selects the Model Description and provides to Fox Customer Service

Frequency (in MHz)
Resolutions to 6 places
past the decimal point
H
= HCMOS
L
= LVDS
P
= LVPECL
C

Q
= Quartz
5
= 5 x 3.2mm
7
= 7 x 5mm
3
= 3.3 V
2 = 2.5 V
M
= LVDS

0
= ± 100 PPM

(-20 ~ +70°C)
blank
= -20°C to +70°C
R
= -40°C to +85°C
STEP #2:
The Fox Customer Service team provides a customer specific Part Number
Fox Part Number
The 1
st
Field
for use on their Bill Of Materials (BOM).
(The assigned Fox Part Number must be on the BOM – not the above Model Description)
(This will ensure receipt of the proper part)
Product Code #
The 3
rd
Field
767 = FXO–HC5
Fox Internally Generated Number
768 = FXO–HC7
(If any specification changes,
770 = FXO–LC5
the last digits change)
nd
771 = FXO–LC7
The 2 Field
(The same specs for a different customer
773 = FXO–PC5
The Customer’s Frequency
also changes the last digits)
774 = FXO–PC7
