FEMTOCLOCKS™  
SAS/SATA CLOCK GENERATOR  
ICS843241  
GENERAL DESCRIPTION  
FEATURES  
The ICS843241 is a low jitter, high performance clock  
• Designed for use in SAS-2 systems  
ICS  
HiPerClockS™  
generator and a member of the FemtoClocks™ family  
of silicon timing products.The ICS843241 is designed  
• Up, down and center spread spectrum clocking  
• One differential 3.3V or 2.5V LVPECL output pair  
for use in the SAS-2 interconnect and the three  
transport protocols that use the SAS-2 interconnect:  
• Selectable output frequencies: 75MHz, 100MHz, 150MHz,  
300MHz  
Serial SCSI Protocol (SSP), Serial ATA Tunneled Protocol (STP),  
and Serial Management Protocol (SMP). The ICS843241 has  
excellent (<1ps) RMS phase jitter, over the SAS defined  
integration range. The ICS843241 uses an external, 25MHz,  
parallel resonant crystal to generate three selectable output  
frequencies: 75MHz, 100MHz, 150MHz, and 300MHz. This sili-  
con based approach provides excellent frequency stability and  
reliability. The ICS843241 features up, down, and center spread  
spectrum (SSC) clocking techniques. The up, down and center  
SSC will be required in the SAS-2 applications that have three  
clock trees in the HBA and expander ASICs (see Applications  
Information section, Figure 3).  
• RMS phase jitter @ 75MHz, (900kHz – 7.5MHz):  
0.70ps (typical)  
• 3.3V or 2.5V operating supply  
• 0°C to 70°C ambient operating temperature  
• Available in lead-free (RoHS 6) packages
