CS9L/CSPL SERIES:  ULTRA HF CLOCK OSCILLATOR, PECL, +3.3 VDC or +2.5VDC
DESCRIPTION:  A crystal controlled, high frequency, highly stable oscillator, adhering to Positive Emitter 
Coupled Logic (PECL) Standards and fundamental crystal or analog multiplication technologies. 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.
