VS2 SERIES: VCXO OSCILLATOR, HCMOS, +5.0 VDC, 7x5mm Package
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 multiple clocks. The device is
contained in a sub-miniature, very low profile, leadless ceramic SMD package with 6 gold contact pads. This
miniature 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;
" +5.0 VDC HCMOS
" Frequency Range from 1 to 51.84 MHz
" Miniature Ceramic SMD Package Available on Tape and Reel
" Lead Free
