IDT8N4SV76CCD
REVISION B NOVEMBER 20, 2013 1 ©2013 Integrated Device Technology, Inc.
General Description
The IDT8N4SV76 is an LVDS 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.
