FEMTOCLOCK® CRYSTAL-TO-3.3V,  
2.5V LVPECL CLOCK GENERATOR  
ICS843251I-12  
GENERAL DESCRIPTION  
FEATURES  
The ICS843251I-12 is a 10Gb Ethernet Clock Generator. The  
ICS843251I-12 uses an 18pF parallel resonant crystal over the  
range of 23.2MHz - 30MHz. For Ethernet applications, a 25MHz  
crystal is used. The ICS843251I-12 uses IDT’s 3rd generation  
low phase noise VCO technology, and can achieve <1ps rms  
phase jitter performance over the 1.875MHz - 20MHz integration  
range. The ICS843251I-12 is packaged in a small 8-pin TSSOP,  
making it ideal for use in systems with limited board space.  
One Differential LVPECL output  
Crystal oscillator interface, 18pF parallel resonant crystal  
(23.2MHz - 30MHz)  
Output frequency range: 290MHz - 750MHz
