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
