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:
