CLD/CLDP SERIES: CLOCK OSCILLATOR, LVDS, +3.3 VDC or +2.5VDC
DESCRIPTION: A crystal controlled, high frequency, highly stable oscillator, adhering to Low Voltage
Differential Signaling (LVDS) 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.
