Model Selection Guide & Fox Part Number
STEP #1: Customer selects the Model Description and provides to Fox Customer Service
Model Description
F X O L C 7 3 6 R 7 8 1 . 2 5 Frequency (in MHz)
Resolutions to 6 places
past the decimal point
H = HCMOS C = Ceramic 5 = 5 x 3.2mm 3 = 3.3 V 0 = 100 PPM blank = -20C to +70C
L = LVDS Q = Quartz 7 = 7 x 5mm 2 = 2.5 V 5 = 50 PPM R = -40C to +85C
P = LVPECL 6 = 25 PPM
M = LVDS (pin 2 E/D) 8 = 20 PPM (-20 ~ +70C)
Q = LVPECL (pin 2 E/D)
nd
X = HCMOS (comp 2 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)
