VCXO Page 1 of 3 REV D. VS4 SERIES: VCXO OSCILLATOR, HCMOS, +3.3 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.
