IDT8N3SV75 Datasheet, PDF (1/19 Pages) Integrated Device Technology – Fourth generation FemtoClock

LVPECL Frequency-Programmable VCXO IDT8N3SV75
DATASHEET
General Description
The IDT8N3SV75 is a LVPECL Frequency-Programmable VCXO
with very flexible frequency and pull-range programming capabilities.
The device uses IDT’s fourth generation FemtoClock^® NG
technology for an optimum of high clock frequency and low phase
noise performance. The device accepts 2.5V or 3.3V supply and is
packaged in a small, lead-free (RoHS 6) 6-lead ceramic 5mm x 7mm
x 1.55mm package.
The device can be factory-programmed to any frequency in the
range of 15.476MHz to 866.67MHz and from 975MHz to 1,300MHz
to the very high degree of frequency precision of 218Hz or better.
The extended temperature range supports wireless infrastructure,
telecommunication and networking end equipment requirements.
