The 8V41N012A 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, sRIO, XAUI, SerDes reference clocks and the clocks for both the Gigabit Ethernet MAC and PHY. The output frequencies are generated from a 25MHz external input source or an external 25MHz parallel resonant crystal. The industrial temperature range of the 8V41N012A supports telecommunication, networking, and storage requirements.
 

Features

  • Ten selectable 100MHz, 125MHz, 156.25MHz and 312.5MHz clocks for PCI Express, sRIO and GbE, HCSL interface levels
  • One single-ended QG LVCMOS/LVTTL clock output at 125MHz
  • One single-ended QF LVCMOS/LVTTL clock output at 50MHz
  • Two single-ended QREFx LVCMOS/LVTTL outputs at 25MHz
