General Description

The IDT8N3D085 is a LVPECL Dual Frequency-Programmable

Crystal Oscillator with very flexible frequency 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 programmed to any frequency in the range from

15.476MHz to 866.67MHz and from 975MHz to 1,300 MHz and

supports a very high degree of frequency precision of 218Hz or

better. One of two pre-set output frequencies is selected by the

FSEL pin.The extended temperature range supports wireless

infrastructure, telecommunication and networking end equipment

requirements.
