FNSAS2075
3.3V CMOS Low-Jitter 75 MHz SAS-2 XO
ASSP XO™ for Storage
7.0 x 5.0mm Ceramic SMD
Package: (Scale: none, Dimensions are in mm)
Product Features
• Very low phase jitter - 0.5ps RMS
Recommended Land Pattern:
• Thicker crystal for improved reliability
• Low output current - 20mA max.
• Low power stand by mode
• Industrial Temperature Range
• Pb-free & RoHS compliant
Product Description
This is an enhanced high-frequency 3.3V,
75MHz crystal clock oscillator with superb
jitter and low operating current for Serial
Attached SCSI (SAS-1 & SAS-2) applications.
Pin Functions:
The output clock signal, generated internally
with a patented oscillator design, is
compatible with LVCMOS logic levels.
