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.
