8T49N1083NLGI

Overview

The 8T49N1083NLGI is a frequency translator integrated circuit manufactured by Renesas Electronics. It belongs to the FemtoClock NG series and functions as a clock generator or jitter cleaner. The device supports input formats including HCSL, LVDS, and LVPECL, with LVPECL outputs. It operates within a supply voltage range of 2.375V to 3.465V and is rated for an operating temperature range of -40°C to 85°C. The component is housed in a 32-VFQFN exposed pad package.

Feature Summary

• Supports multiple input interface standards including HCSL, LVDS, and LVPECL
• Provides LVPECL output signals for downstream clock distribution
• Operates on a single 2.5V nominal power supply rail

Applications

• High-speed data communication systems requiring precise clock translation
• Telecommunications infrastructure equipment
• Industrial control systems utilizing differential clock signals

Procurement Notes

This component is identified as End-of-Life (EOL) by the manufacturer. Production has been discontinued, and no new inventory is available from official channels. Procurement should focus on verifying the authenticity of existing stock from authorized distributors. Buyers must confirm the specific manufacturing date code and lot history due to the age of available units. Replacement planning is strongly recommended given the permanent discontinuation status.

Selection Notes

Engineers selecting this part should verify compatibility with existing system voltage levels, specifically the 2.5V requirement. The transition from previous IDT branding to Renesas requires checking updated datasheets for any parameter shifts. Designers must ensure the PCB layout accommodates the 32-VFQFN package thermal requirements. Alternative solutions should be evaluated if long-term supply stability is a critical project constraint.

Part Context

The 8T49N1083NLGI is part of the FemtoClock NG family, designed for low-jitter clock generation and translation. Originally introduced under the IDT brand before Renesas acquired the semiconductor assets, this specific model serves as a frequency translator. It bridges different clock domains in complex electronic systems, ensuring signal integrity across high-speed interfaces.
