IDT8N4S273
DATA SHEET
General Description
The IDT8N4S273 is a Factory 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 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, telecommunication and networking end equipment
requirements.

What is special about low power mode LPM1
This is a common table of LPM mode. In this table, SCG0 is 1 in LPM1 mode. It is generally believed that SCG0 uses DCO off, so simply speaking, DCO is turned off in LPM1 mode. But is it really turned ...
