CS9/CSP SERIES: 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. 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 or +2.5VDC PECL
" Frequency Range from 50.000 to 315 MHz
" No multiplication
" Miniature Ceramic SMD Package Available on Tape and Reel
" Lead Free and ROHS Compliant
