8T49N222B-004NLGI8

Overview

The 8T49N222B-004NLGI8 is a clock generator from the FemtoClock NG series manufactured by Renesas Electronics Corporation. It features a single circuit with a maximum frequency of 1GHz and supports differential input/output signals. The device accepts HCSL, LVDS, LVHSTL, LVPECL, or crystal inputs and provides LVDS outputs in a 3:2 input-to-output ratio. Powered by a 2.375V to 3.465V supply, it operates within -40°C to 85°C and is housed in a 48-VFQFN exposed pad package.

Feature Summary

• Maximum output frequency of 1GHz
• Supports multiple input types including HCSL, LVDS, LVHSTL, LVPECL, and crystal
• Differential LVDS output configuration
• Integrated PLL with bypass capability

Applications

• High-speed data communication systems requiring precise clocking
• Networking equipment utilizing LVDS interfaces
• Industrial control systems operating in extended temperature ranges

Procurement Notes

Verify component status as listings indicate potential end-of-life notifications for the 8T49N222 family. Confirm RoHS3 compliance and moisture sensitivity level (MSL 3) prior to procurement. Check for official Product Change Notices regarding assembly site or marking changes to ensure supply chain continuity.

Selection Notes

Select this model when a 1GHz LVDS output is required with flexible input compatibility including LVHSTL and crystal sources. Ensure the design accommodates the 48-VFQFN footprint and 2.375V-3.465V power domain. Verify that the 3:2 input-to-output ratio aligns with system timing requirements compared to other FemtoClock variants.

Part Context

This component belongs to the FemtoClock NG series, designed for low-jitter clock generation. The 8T49N222B variant specifically targets high-frequency applications with LVDS outputs. It shares the core architecture with other 8T49N222 models but differs in specific ordering suffixes that define input/output configurations and factory pre-programmed frequencies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult Renesas official resources for direct replacements or evaluate similar FemtoClock NG devices with matching pinouts and electrical specifications.
