ICS844002I-01  
FEMTOCLOCKS™ CRYSTAL-TO-  
LVDS FREQUENCY SYNTHESIZER  
Integrated  
Circuit  
Systems, Inc.  
GENERAL DESCRIPTION  
FEATURES  
The ICS844002I-01 is a 2 output LVDS Two LVDS outputs  
Synthesizer optimized to generate Ethernet  
ICS  
• Selectable crystal oscillator interface  
or LVCMOS/LVTTL single-ended input  
HiPerClockS™  
reference clock frequencies and is a mem-  
ber of the HiPerClocksTM family of high  
performance clock solutions from ICS. Using a  
• Supports the following output frequencies: 156.25MHz,  
125MHz, 62.5MHz  
25MHz, 18pF parallel resonant crystal, the 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 ICS’ 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 and RoHS/Lead-Free compliant  
packages
