Model Selection Guide & Fox Part Number
STEP #1: Customer selects the Model Description and provides to Fox Customer Service
Model Description
FXU L C 5 3 5 R 6 2 2.0 8 Frequency (in MHz)
Resolutions to 6 places
past the decimal point
L = LVDS C = Ceramic 5 = 5 x 3.2mm 3 = 3.3 V 0 = 100 PPM blank = -20C to +70C
M = LVDS (pin 2 E/D)
5 = 50 PPM
R = -40C to +85C
6 = 25 PPM
8 = 20 PPM (-20C to +70C)
STEP #2: The Fox Customer Service team provides a customer specific Part Number
for use on their Bill Of Materials (BOM).
