8T49N286-997NLGI8

Overview

The 8T49N286-997NLGI8 is a Universal Frequency Translator (UFT) from the FemtoClock NG series by Renesas Electronics. It functions as a clock synthesizer and jitter cleaner, supporting input frequencies up to 1 GHz and providing multiple output configurations. The device utilizes an I2C programming interface for register configuration and supports various differential and single-ended output standards including LVDS, LVPECL, HCSL, and LVCMOS. Designed for high-performance timing applications, it operates within a temperature range of -40°C to +85°C and is housed in a 72-VFQFN exposed pad package.

Feature Summary

• Universal Frequency Translator architecture with integer and fractional-N PLL synthesis capabilities
• Supports multiple input/output voltage levels including LVDS, LVPECL, HCSL, and LVCMOS
• Integrated I2C interface for flexible frequency and configuration programming
• Low phase jitter performance suitable for high-speed serial communication standards

Applications

• High-speed data converter clocking systems
• Telecommunications infrastructure timing
• Test and measurement equipment reference clocks
• Networking switches and routers synchronization

Part Context

This component belongs to the 8T49N286 family of Universal Frequency Translators. The suffix '997' typically denotes specific factory pre-programmed frequency settings or output configurations defined by the manufacturer. It is part of the FemtoClock NG line, which emphasizes low jitter performance for demanding digital interfaces.

Replacement Considerations

Direct pin-to-pin replacements may include other variants within the 8T49N286 family such as 8T49N286A, provided the electrical specifications and pre-programmed frequencies match the design requirements. Verification of the specific order code's internal register map is necessary before substitution.
