8T49N222B-000NLGI

Overview

The 8T49N222B-000NLGI is a FemtoClock NG Universal Frequency Translator manufactured by Renesas Electronics. It operates within a supply voltage range of 2.375V to 3.465V and supports an input frequency ratio of 3:2. The device features one circuit with differential input and output capabilities, supporting HCSL, LVDS, LVHSTL, and LVPECL inputs while providing LVDS outputs. It achieves a maximum frequency of 1GHz and functions reliably across a temperature range of -40°C to +85°C. The component is housed in a 48-VFQFN package with an exposed pad.

Feature Summary

• Supports multiple input standards including HCSL, LVDS, LVHSTL, and LVPECL for flexible system integration.
• Provides differential LVDS outputs to ensure signal integrity in high-speed applications.
• Features a 3:2 input-to-output frequency ratio for precise clock translation.
• Operates within a wide industrial temperature range from -40°C to +85°C.

Applications

• High-speed serial link clock generation
• Data converter clocking systems
• Telecommunications infrastructure timing
• Test and measurement equipment

Procurement Notes

Verify the specific suffix '000' against official Renesas documentation to confirm pinout and electrical characteristics, as suffixes often denote specific configuration or packaging variations. Ensure compatibility with the required input/output voltage levels and interface standards before procurement. Confirm availability through authorized distributors, as lead times may vary based on production schedules.

Selection Notes

Select this component when a single-channel clock translator with a 3:2 ratio is required. It is suitable for designs needing support for various input formats like LVDS and LVPECL. Consider the 48-VFQFN package size for board space constraints. Verify that the 1GHz maximum frequency meets the target application's speed requirements.

Part Context

This part belongs to the FemtoClock NG family, designed for low-jitter clock synthesis and distribution. The 8T49N222B series specifically targets universal frequency translation needs in high-performance digital systems. It integrates programmable features to adapt to diverse clocking architectures without external components.

Replacement Considerations

Consult Renesas official substitution guides for direct replacements. Generic equivalents may not match the specific 3:2 ratio or input format support. Verify pin compatibility and electrical specifications before considering alternative parts.
