3.3V PECL Low Jitter 150MHz SAS-2 XO PDSAS2150
Application Specic Crystal Oscillator 5.0 x 3.2mm
TM
Product Features
• Very low phase jitter - 0.5ps RMS
• Thicker crystal for improved reliability
•Pb-free & RoHS compliant
•Industrial temperature range
Product Description
The PD 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 5.0 x 3.2mm surface-mount
ceramic package.
Applications
• SAS-2 Host Bus Adapter (HBA)
• SAS-2 Expander
• SAS-2 RAID System
