CLD SERIES: CLOCK OSCILLATOR, LVDS, +3.3 VDC
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.
APPLICATIONS AND FEATURES:
Infiniband; 10GbE; Network Processors; SOHO Routing; Switches; WAN Interfaces
Common Frequencies: 106.25 MHz; 125 MHz; 150 MHz; 155.52 MHz; 156.25 MHz; 161.1328 MHz
+3.3 VDC LVDS
Frequency Range from 80 to 250 MHz
