LVPECL Dual-Frequency
Programmable VCXO
General Description
The IDT8N3DV85 is a LVPECL Dual-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 two frequencies 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 output frequency is selected by the FSEL pin. The extended
temperature range supports wireless infrastructure, telecommuni-
cation and networking end equipment requirements.
