CLD/CLDP SERIES: CLOCK OSCILLATOR, LVDS, +3.3 VDC or +2.5VDC
DESCRIPTION: A crystal controlled, high frequency, highly stable oscillato r, adhering to Low Voltage
Differential Signaling (LVDS) Standa rds. The output can be Tri-stated to facilita t e 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 MH z; 150 MHz; 155.52 MH z; 156.25 MHz; 161.1328 MH z
" +3.3 VDC or +2.5VDC LVDS
" Frequency Range from 50.000 to 315 MHz
" No multiplication
" Miniature Ceramic SMD Package Available on Tape and Reel
" Lead Free and ROHS Compliant
