FEMTOCLOCKS™ CRYSTAL-TO-3.3V,  
2.5V LVPECL CLOCK GENERATOR  
ICS843251I-14  
GENERAL DESCRIPTION  
FEATURES  
The ICS843251I-14 is a 10Gb Ethernet Clock  
One Differential LVPECL output  
ICS  
Generator and a member of the HiPerClocksTM  
family of high performance devices from IDT. The  
ICS843251I-14 uses an 18pF parallel resonant  
crystal over the range of 22.4MHz - 27.2MHz. For  
Crystal oscillator interface, 18pF parallel resonant crystal  
(22.4MHz - 27.2MHz)  
HiPerClockS™  
Output frequency ranges:  
Ethernet applications, a 25MHz crystal is used. The device has  
excellent <1ps phase jitter performance, over the 1.875MHz -  
20MHz integration range. The ICS843251I-14 is packaged in a  
small 8-pin TSSOP, making it ideal for use in systems with  
limited board space.  
FREQ_SEL = 1: 560MHz to 680MHz  
FREQ_SEL = 0: 140MHz to 170MHz  
VCO range: 560MHz - 680MHz  
RMS phase jitter @ 156.25MHz, using a 25MHz crystal  
(1.875MHz - 20MHz): 0.49ps (typical) @ 3.3V  
3.3V or 2.5V operating supply  
-40°C to 85°C ambient operating temperature  
Available in both standard (RoHS 5) and lead-free (RoHS 6)  
packages
