General Description

The IDT8N3S272 is a 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 factory programmed to any frequency 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. The extended temperature range supports wireless

infrastructure, telecommun- ication and networking end equipment

requirements.
