LVDS Frequency-Programmable

Crystal Oscillator

IDT8N4S270

DATASHEET

General Description

Features

The IDT8N4S270 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.

• Fourth generation FemtoClock^®NG technology

• Factory-programmable clock output frequency from 15.476MHz to

866.67MHz and from 975MHz to 1,300MHz

• Frequency programming resolution is 218Hz and better

• One 2.5V, 3.3V LVDS clock output

• Output enable control (positive polarity), LVCMOS/LVTTL

compatible

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.

• RMS phase jitter @ 231.25MHz (12kHz - 20MHz): 

0.48ps (typical), integer PLL feedback configuration

• RMS phase jitter @ 231.25MHz (1kHz - 40MHz): 

0.50ps (typical), integer PLL feedback configuration

• 2.5V or 3.3V supply

• -40°C to 85°C ambient operating temperature

• Available in a lead-free (RoHS 6) 6-pin ceramic package
