DATA SHEET
General Description
Features
The IDT8N0DV85 is a LVCMOS 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.

Two factory-programmed output frequencies
The device can be factory-programmed to any two frequencies in the
range of 15.476MHz to 260MHz 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, telecommunication and networking end equipment
requirements.
