VS9P: PLL LVPECL SERIES: LOW COST UHF/HF VCXO, LVPECL, +3.3 VDC
DESCRIPTION: A low cost voltage control crystal oscillator, high frequency, highly stable oscillator, adhering to Low Voltage
Differential Signaling (LVPECL) Standards. The output can be Tri-stated to facilitate testing or combined multiple clocks. The
device is contained in a sub-miniature, very l ow 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; Fiber Channel; SATA; 10GbE; Network Processors; SOHO Routing; Switches;
" Common Frequencies: 150 MHz; 156.25 MHz; 155.52 MHz; 161.1328 MHz; 212.5MHz; 312.5MHz
" +3.3 VDC LVPECL
" Frequency Range from 750KHz to 800 MHz
" PLL multiplication (F>25MHz)
" Mini ature Ceramic SMD Package Available on Tape and Reel
" Lead Free and ROHS Compliant
