8V49NS0412NLGI

Overview

The 8V49NS0412NLGI is a VersaClock 6 programmable clock generator manufactured by Renesas Electronics. It features 12 outputs with a maximum frequency of 2.5 GHz and supports input frequencies up to 50 MHz. The device operates within a supply voltage range of 3.135 V to 3.465 V, consuming approximately 73 mA. It exhibits a typical jitter of 87 fs and functions reliably in temperatures from -40°C to +85°C. Packaged in a 64-pin VFQFN, it integrates configuration storage capabilities for high-performance timing applications.

Feature Summary

• Generates up to 12 output clocks with frequencies reaching 2.5 GHz
• Supports multiple output formats including LVPECL, LVDS, HCSL, and LVCMOS
• Configurable via I²C interface or stored in internal OTP memory
• Low power consumption with core voltage options of 1.8V, 2.5V, or 3.3V

Applications

• High-speed networking equipment and routers
• Data communications infrastructure
• Industrial computing systems
• PCI Express compliant designs

Procurement Notes

Verify the specific suffix 'NLGI' against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with required I²C addressing and boot configurations before procurement. Cross-reference the Mouser part number 972-8V49NS0412NLGI for current availability status.

Selection Notes

Select this component when requiring a single reference clock to generate multiple independent output frequencies up to 2.5 GHz. Verify that the system requires the specific 64-pin VFQFN footprint. Confirm that the 87 fs jitter specification meets the signal integrity requirements of the target application.

Part Context

This part belongs to the VersaClock 6 family, representing Renesas' sixth generation of programmable clock technology. It is designed to replace older fixed-frequency oscillators in complex digital systems requiring precise timing synchronization across multiple buses.

Replacement Considerations

Direct replacements include other VersaClock 6 variants such as the 8V49NS0312NLGI, provided the output count and frequency specifications align with the design requirements. Verify pin-to-pin compatibility and register mapping differences.
