VSY SERIES: VCXO OSCILLATOR, HCMOS, +2.5 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.
