LVDS Dual Frequency Programmable

Crystal Oscillator

IDT8N4D085

DATASHEET

General Description

The IDT8N4D085 is an LVDS Dual Frequency-Programmable Crys-

tal Oscillator with very flexible frequency programming capabilities.

The device uses IDT’s fourth generation FemtoClock

NG technolo-

gy for an optimum of high clock frequency and low phase noise per-

formance. 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 in the range from 15.476MHz

to 866.67MHz and from 975MHz to 1,300MHz 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, telecommunica-

tion and networking end equipment requirements.
