FXO-HC73 Series
Model Selection Guide & Fox Part Number
STEP #1: Customer selects the Model Description and provides to Fox Customer Service
Model Description
F X O – H C 7 3 6 R – 1 0 6 . 2 5 Frequency (in MHz)
Resolutions to 6 places
past the decimal point
H = HCMOS
L = LVDS
C = Ceramic
Q = Quartz
5 = 5 x 3.2mm
7 = 7 x 5mm
3 = 3.3 V
2 = 2.5 V
0 = ± 100 PPM
5 = ± 50 PPM
6 = ± 25 PPM
blank = -20°C to +70°C
R = -40°C to +85°C
8 = ± 20 PPM
M = LVDS (pin 2 E/D)
(-20 ~ +70°C)
Q = LVPECL (pin 2 E/D)
X = HCMOS (comp 2nd Output)
STEP #2: The Fox Customer Service team provides a customer specific Part Number
for use on their Bill Of Materials (BOM).
Fox Part Number (The assigned Fox Part Number must be on the BOM – not the above Model Description)
(This will ensure receipt of the proper part)
The 1st Field
Product Code #
7 6 8 – 1 0 6 . 2 5 – 2 0
The 3rd Field
Fox Internally Generated Number
(If any specification changes,
the last digits change)
(The same specs for a different customer
also changes the last digits)
767 = FXO–HC5
768 = FXO–HC7
770 = FXO–LC5
771 = FXO–LC7
773 = FXO–PC5
774 = FXO–PC7
The 2nd Field
The Customer’s Frequency
This example, FXO-HC736R-106.25 = HCMOS Output, Ceramic 7 x 5mm Package, 3.3V,
±25 PPM Stability, -40 to +85°C Temperature Range, at 106.25 MHz
