The IDT8V41N012I 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 IDT8V41N012I 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
  • Selectable external crystal or differential (single-ended) input source
  • Crystal oscillator interface designed for 25MHz, parallel resonant crystal
  • Differential CLK, nCLK input pair that can accept: LVPECL, LVDS, LVHSTL, HCSL input levels
  • Internal resistor bias on nCLK pin allows the user to drive CLK input with external single-ended (LVCMOS/ LVTTL) input levels
  • Supply Modes, (125MHz QG output and 25MHz QREFx outputs): 
    • Core / Output
    • 3.3V / 3.3V
    • 3.3V / 2.5V 
  • Supply Modes, (HCSL outputs, and 50MHz QF output):
    • Core / Output
    • 3.3V / 3.3V
  • -40°C to 85°C ambient operating temperature
  • Lead-free (RoHS 6) packaging
