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.
APPLICATIONS AND FEATURES:
"
Common Frequencies: 16.384 MHz; 19.44 MHz; 27 MHz; 38.88 MHz; 51.84 MHz; 77.76 MHz
"
+3.3 VDC HCMOS
"
Frequency Range from 1 to 125.000 MHz
"
Miniature Ceramic SMD Package Available on Tape and Reel
"
Lead Free and ROHS Compliant
