VA2 SERIES: 9.3X8.5mm VCXO OSCILLATOR, HCMOS, +5.0 VDC

DESCRIPTION: A crystal controlled, high frequency, highly stable, voltage controlled oscillator, adhering to HCMOS

Standards. The output can be Tri-stated to facilitate testing or combined multipl e clocks. This oscillator is ideal for

today's automated assembly environments.

APPLICATIONS AND FEATURES:

Common Frequencies: 16.384 MHz; 19.44 MHz; 27 MHz; 38.88 MHz; 51.84 MHz; 77.76 MHz

+5.0 VDC HCMOS

Frequency Range from 1 to 100 MHz
