Overview
Description
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.
Features
- Ten 100MHz clocks for PCI Express, HCSL interface levels
- One single-ended QG LVCMOS/LVTTL clock output at 125MHz
