DATA SHEET  
FEMTOCLOCKS™ CRYSTAL-TO-LVDS CLOCK  
ICS844252-04  
GENERATOR  
GENERAL DESCRIPTION  
FEATURES  
Two differential LVDS outputs  
The ICS844252-04 is a 10Gb/12Gb Ethernet  
ICS  
HiPerClockS™  
Clock Generator and  
a member of the  
Crystal oscillator interface designed for  
18pF parallel resonant crystals  
HiPerClocksTM family of high performance  
devices from ICS. The ICS844252-04 can  
synthesize 10 Gigabit Ethernet and 12 Gigabit  
Crystal input frequency range: 19.33MHz - 30MHz  
Output frequency range: 145MHz - 187.5MHz  
VCO frequency range: 580MHz - 750MHz  
Ethernet with a 25MHz crystal. It can also generate SATA  
and 10Gb Fibre Channel reference clock frequencies with  
the appropriate choice of crystals. The ICS844252-04 has  
excellent phase jitter performance and is packaged in a  
small 16-pin TSSOP, making it ideal for use in systems with  
limited board space.  
RMS phase jitter at 156.25MHz (1.875MHz - 20MHz):  
0.36ps (typical)  
3.3V operating supply  
0°C to 70°C ambient operating temperature  
Industrial temperature information available upon request  
Available in both standard and lead-free compliant  
packages
