VS9P: PLL LVPECL SERIES: LOW COST UHF/HF VCXO, LVPECL, +3.3 VDC
DESCRIPTION: A low cost
voltage control crystal oscillator
, high frequency, highly stable oscillator, adhering to Low Voltage
Differential Signaling (LVPECL) 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.
