CFPV-55 SMD VCXO
ISSUE 4; 23 FEBRUARY 2010 - RoHS 2002/95/EC
Description
A high frequency, surface mount voltage controlled oscillator
▪
(VCXO) in a hermetically sealed ceramic package
Package Outline
7 x 5mm
▪
Frequency Range
12 to 700MHz
▪
Output Compatibility & Load
Tri-state LVPECL
▪
Output Load 50
▪W terminated to +1.3V
Frequency Stabilities
±25ppm, ±50ppm (inclusive of supply voltage and output
▪
load variations over the operating temperature range)
Operating Temperature Ranges
–10 to 70°C (CFPV-55)
▪
–40 to 85°C (CFPV-55I)
▪
Storage Temperature Range

▪
Tri-state Operation
Logic ‘1’ (>Vs-1.10V
▪) to pad 1 disables oscillator output;
when disabled the oscillator goes to the high impedance
state
Logic ‘0’ (<Vs-1.60V) to pad 1 enables oscillator output
▪
No connection to pad 1 enables oscillator output
▪
Voltage Control (pad 1)
+1.65V ±1.5V (positive sense)
▪
Pullability
±150ppm min
▪
Input Impedance (voltage control, pad 1)
60k
