概要
説明
The 8430S803I is a PLL-based clock generator specifically designed for Cavium Networks SoC processors. This high performance device is optimized to generate the processor core reference clock, the DDR reference clocks, the PCI/PCI-X bus clocks, and the clocks for both the Gigabit Ethernet MAC and PHY. The clock generator offers low-jitter, low-skew clock outputs, and edge rates that easily meet the input requirements for the CN30XX/CN31XX/CN38XX/CN58XX processors. The output frequencies are generated from a 25MHz external input source or an external 25MHz parallel resonant crystal. The extended temperature range of the 8430S803I supports telecommunication, networking, and storage requirements.
