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
