CS9 SERIES: CLOCK OSCILLATOR, PECL, +3.3 VDC
DESCRIPTION: A crystal controlled, high frequency, highly stable oscillator, adhering to Positive Emitter
Coupled Logic (PECL) 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.
