Product Description
The PN Series 3.3V crystal clock oscillator
achieves superb jitter and stability over a broad
range of operating conditions and frequencies.
The output clock signal, 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.
Part Ordering Information:
PN XXX YYYY
A: Product Family
B: XXX = Frequency Code
C: YYYY = Specification Code
Applications
The PN Series is an ideal reference clock for
high-speed applications requiring includes:
• 1/10 Gigabit Ethernet
• 2/4/10G Fibre Channel
• Serial Attached SCSI (SAS)
