Data Sheet
General Description
Features
The 8413S12I-100 is a PLL-based clock generator specifically
designed for Cavium Networks Octeon II processors. This high
performance device is optimized to generate the processor core
reference clock, the PCI-Express reference clocks and the clocks for
both the Gigabit Ethernet MAC and PHY. The clock generator offers
ultra low-jitter, low-skew clock outputs, and edge rates that easily
meet the input requirements for the CN63XX and CN68XX series of
processors. The output frequencies are generated from a 25MHz
external input source or an external 25MHz parallel resonant crystal.
The industrial temperature range of the 8413S12I-100 supports
telecommunication, networking, and storage requirements.
