VS9: FUNDAMENTAL LVPECL SERIES: HF VCXO, LVPECL, +3.3 VDC
DESCRIPTION: A voltage crystal controlled 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 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; SONET/SDH
"# Common Frequencies: 38.88 MHz; 77.76MHz; 155.52 MHz; 156.25 MHz; 161.1328 MHz;
"# +3.3 VDC LVPECL
"# Frequency Range from 1.000 to 180.000 MHz
"# No Multiplication is used, low phase noise and jitter
"# Miniature Ceramic SMD Package Available on Tape and Reel
"#Lead Free and ROHS Compliant
