Description
Our QEV51-KO is a sinewave Voltage Controlled Crystal Oscillator in a
package 20 x 20 x 10 m m which is designed for industrial tem perature range
of -40° C to +85° C with a sinusoidal output. It allows an upper frequency of
200 MHz by using an overtone quartz resonator in a sealed package and
a pulling range up to ±100 ppm .
This type of product is well suited for very low phase noise applications
(typically -120 dBc/Hz @ 100 Hz and typically -155 dBc/Hz @ 10 kHz for
F= 150 MHz). Using ACMOS technology, the QEV51-KH offers the sam e
perform ance up to 120 MHz.
Frequency range
14 MHz to 200 MHz
