C9P: PLL LVPECL SERIES: ULTRA HF CLOCK OSCILLATOR, LVPECL, +3.3 VDC
DESCRIPTION: A crystal controlled, 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.
