Description
The PI6LC48P02 is a 2-output LVPECL synthesizer optimized
to generate Fibre Channel, Ethernet and storage reference clock
frequencies and is a member of Pericom’s HiFlex family of high
performance clock solutions. Using a 26.5625MHz crystal, the
most popular Fibre Channel (FC) frequencies can be generated
based on the settings of 2 frequency select pins. Using 25MHz
Xtal, most Ethenrnet frequencies inckuding 100MHz can be
generated, while using 26.041667MHz Xtal, 156.25MHz can be
generated for Networking applications.
The PI6LC48P02 uses Pericom’s proprietary low phase noise
PLL technology to achieve ultra low phase jitter, it is ideal for
Networking, data center, and storage systems.
Applications
ÎÎNetworking and Data Center Server systems
ÎÎFibre Channel (FC) and Storage systems
