Product Description
The SN series 3.3V, 150MHz crystal clock
oscillator achieves superb jitter for Serial
Attached SCSI (SAS-1 & SAS-2) applications.
The output clock signal, generated internally
with a patented oscillator design, is
compatible with LVPECL logic levels. The
device, available on tape and reel, is
contained in a 7.0 x 5.0mm surface-mount
ceramic package.

Applications
• SAS-2 Host Bus Adapter (HBA)
• SAS-2 Expander
• SAS-2 RAID System
*Extended high frequency power decoupling is recommended (see test circuit for minimum
recommendation). To ensure optimal performance, do not route RF traces beneath the
package.
