FEMTOCLOCKS™ CRYSTAL-TO-  
3.3V LVPECL FREQUENCY SYNTHESIZER  
ICS843204I-01  
GENERAL DESCRIPTION  
FEATURES  
The ICS843204I-01 is a 4 output LVPECL Synthe-  
• Four 3.3V LVPECL outputs  
ICS  
sizer optimized to generate Gigabit Ethernet and  
SONET reference clock frequencies and is a  
member of the HiPerClocksTM family of high  
performance clock solutions from IDT. Using a  
• Selectable crystal oscillator interface or clock inputs  
HiPerClockS™  
• Supports the following output frequencies: 155.52MHz  
and 156.25MHz  
19.44MHz and 25MHz, 18pF parallel resonant crystal,  
155.52MHz and 156.25MHz frequencies can be generated.  
The ICS843204I-01 uses IDT’s FemtoClockTM low phase noise  
VCO technology and can achieve 1ps or lower typical RMS  
phase jitter.  
• VCO range: 560MHz - 680MHz  
• RMS phase jitter @ 155.52MHz, using a 19.44MHz crystal  
(12kHz - 13MHz): 0.6ps (typical)  
• RMS phase jitter @ 156.25MHz, using a 25MHz crystal  
(1.875MHz - 20MHz): 0.7ps (typical)  
• Full 3.3V supply mode  
• -40°C to 85°C ambient operating temperature  
• Available in both standard (RoHS 5) and lead-free (RoHS 6)  
packages
