Product Description
The PX 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 non-PLL oscillator design, is compatible
with LVDS logic levels. The device, available
on tape and reel, is contained in a 7x5mm
surface-mount ceramic package.
Applications
The PX Series is ideal for high-speed
applications requiring low jitter, including:
1/10 Gigabit Ethernet•
2/4/10G FibreChannel•
Serial Attached SCSI (SAS)•
Server & Storage platforms•
SONET/SDH linecards•
Passive Optical Network (PON) devices•
HD Video Systems•
