VS9M: ANALOG MULTIPLIED LVPECL SERIES: ULTRA HF VCXO, LVPECL, +3.3 VDC
DESCRIPTION: A crystal controlled, 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 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; 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, 622.080 MHz
" +3.3 VDC LVPECL
" Frequency Range from 750KHz to 800MHz
" Low Phase Noise Analog Multiplication
