Description
Our QEV51-KO is a sinewave Voltage Controlled Crystal Oscillator in a
package 20 x 20 x 10 mm which is designed for industrial temperature 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 same
performance up to 120 MHz.
