8V41N012NLGI

Overview

The 8V41N012A is a PLL-based clock generator designed for Cavium Networks Octeon II processors. It generates processor core, PCI-Express, sRIO, XAUI, SerDes, and Gigabit Ethernet MAC/PHY reference clocks from a 25MHz external source or crystal. The device features ten selectable HCSL outputs (100MHz, 125MHz, 156.25MHz, 312.5MHz), one single-ended QG LVCMOS/LVTTL output at 125MHz, one QF LVCMOS/LVTTL output at 50MHz, and two QREFx LVCMOS/LVTTL outputs at 25MHz. It operates in an industrial temperature range of -40°C to 85°C within a 72-VFQFPN package.

Feature Summary

• Ten selectable HCSL outputs for PCI Express, sRIO, and GbE applications
• Single-ended QG (125MHz) and QF (50MHz) LVCMOS/LVTTL outputs
• Two single-ended QREFx (25MHz) LVCMOS/LVTTL outputs
• Supports differential CLK/nCLK inputs (LVPECL, LVDS, LVHSTL, HCSL) or 25MHz parallel resonant crystal

Applications

• Cavium Networks Octeon II processor systems
• Telecommunication equipment
• Networking infrastructure
• Storage systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and packaging details. Confirm that the component meets RoHS 6 lead-free requirements and check for any moisture sensitivity level restrictions during storage and handling.

Selection Notes

Select this component when designing for Cavium Octeon II architectures requiring precise timing for PCIe, sRIO, and Ethernet interfaces. Ensure the design supports the required supply voltage configurations (3.3V or 2.5V) for the respective output banks and input sources.
