FEMTOCLOCKS– CRYSTAL-TO-  
LVDS FREQUENCY SYNTHESIZER  
ICS844002I-01  
General Description  
Features  
The ICS844002I-01 is a 2 output LVDS Synthesizer  
Two differential LVDS outputs  
S
IC  
optimized to generate Ethernet reference clock  
frequencies and is a member of the HiPerClocksTM  
family of high performance clock solutions from IDT.  
Using a 25MHz, 18pF parallel resonant crystal, the  
Selectable crystal oscillator interface or  
HiPerClockS™  
single-ended LVCMOS/LVTTL input  
Supports the following output frequencies: 156.25MHz,  
125MHz, 62.5MHz  
following frequencies can be generated based on the 2 frequency  
select pins (F_SEL[1:0]): 156.25MHz, 125MHz and 62.5MHz. The  
ICS844002I-01 uses IDT’s 3rd generation low phase noise VCO  
technology and can achieve <1ps typical rms phase jitter, easily  
meeting Ethernet jitter requirements. The ICS844002I-01 is  
packaged in a small 20-pin TSSOP package.  
VCO range: 560MHz – 680MHz  
RMS phase jitter @ 156.25MHz, using a 25MHz crystal  
(1.875MHz – 20MHz): 0.41ps (typical)  
Full 2.5V supply mode  
-40°C to 85°C ambient operating temperature  
Available in both standard (RoHS 5) and lead-free (RoHS 6)  
packages
