Product Description
The SN Series 3.3V crystal clock oscillator
achieves superb jitter and stability over a broad
range of operating conditions and frequencies.
The output clock signal, generated internally
with a patented oscillator design, is compatible
with LVPECL logic levels. The device contains
a divide-by-2 RateSelect™ function that toggles
the output frequency and is available on
tape and reel, is contained in a 7.0 x 5.0mm
surface-mount ceramic package.
Applications
The SN Series is ideal for high-speed
applications requiring low jitter, including:
1/10 Gigabit Ethernet•
2/4/10G Fibre Channel•
Serial Attached SCSI (SAS)•
Server & Storage platforms•
SONET/SDH linecards•
Passive Optical network (PON) Systems•
