FemtoClock® NG  
Crystal-to-LVCMOS/LVTTL Clock  
840N021  
DATA SHEET  
General Description  
Features  
The 840N021 is a LVCMOS/LVTTL clock synthesizer designed for  
Ethernet applications. The device generates a 125MHz clock signal  
from a 25MHz crystal with excellent phase jitter performance. The  
device uses IDT’s fourth generation FemtoClock® NG technology for  
an optimum of high clock frequency, low phase noise performance  
and low power consumption.The device supports 2.5V or 3.3V  
voltage supply and is packaged in a small, lead-free (RoHS 6) 8-lead  
TSSOP package. The extended temperature range supports  
wireless infrastructure, telecommunication and networking end  
equipment requirements. The device is a member of the  
Fourth generation FemtoClock® NG technology
