8T49N287-002NLGI8

Overview

The 8T49N287-002NLGI8 is a FemtoClock NG Octal Universal Frequency Translator manufactured by Renesas Electronics. It functions as a clock generator and jitter cleaner within the 8T49N287 series. The device supports multiple input formats including HCSL, LVDS, LVPECL, and crystal inputs, providing eight differential LVPECL outputs. It operates on a supply voltage range of 2.375V to 3.465V and is rated for an industrial temperature range of -40°C to +85°C. The component is housed in a 40-VFQFN package with an exposed pad.

Feature Summary

• Octal output configuration with eight differential LVPECL clocks
• Universal input support for HCSL, LVDS, LVPECL, and crystal sources
• Integrated jitter cleaning and frequency translation capabilities
• RoHS3 compliant construction

Applications

• High-performance networking equipment requiring precise clock distribution
• Telecommunications infrastructure utilizing GR.1244 Stratum standards
• Data center server platforms needing low-jitter clock synthesis

Procurement Notes

This component is listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock this specific part number in all regions. Verification of current lifecycle status and alternative sourcing options is required before procurement planning.

Selection Notes

Designers should verify compatibility with existing system clock architectures, specifically regarding the LVPECL output swing and input signal requirements. Due to the EOL status, engineering change orders or redesigns using successor models from the FemtoClock NG family may be necessary for new production runs.

Part Context

The 8T49N287 series belongs to Renesas' FemtoClock NG line, designed for high-frequency applications requiring superior jitter performance. This specific model variant provides octal outputs, distinguishing it from lower-output variants like the 8T49N286A. The suffix '002NLGI8' denotes specific packaging and material compliance details.

Replacement Considerations

Potential substitutes include other members of the 8T49N287 family or the 8T49N240 series for jitter attenuation. Specific cross-references should be validated against pinout and electrical parameter compatibility.
