VS9L: PLL LVPECL SERIES: ULTRA HF VCXO, LVPECL, +3.3 VDC
DESCRIPTION: A 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.
