8T49N285-996NLGI8

Overview

The 8T49N285-996NLGI8 is a Universal Frequency Translator IC from the FemtoClock NG series by Renesas Electronics. It operates as a clock synthesizer and jitter cleaner with a maximum frequency of 1GHz. The device features a single circuit in a 56-VFQFN exposed pad package, supporting differential inputs and outputs. It accepts HCSL, LVCMOS, LVDS, LVHSTL, LVPECL, or crystal inputs and provides HCSL, LVCMOS, LVDS, or LVPECL outputs. Supply voltages range from 2.375V to 2.625V and 3.135V to 3.465V, with an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates a fractional-feedback PLL for jitter attenuation and frequency translation
• Supports multiple input and output voltage standards including LVDS and LVPECL
• Designed for high-performance timing applications requiring low phase noise

Applications

• Telecommunications base stations
• High-speed data communication interfaces
• Network synchronization equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level (MSL) prior to assembly. Ensure proper ESD handling procedures are followed during storage and installation. Check for recent production change notices (PCN) affecting die revision or marking updates.

Selection Notes

Select this model when a single-channel universal frequency translator with 1GHz capability is required. Consider the 56-VFQFN package constraints and dual-voltage supply requirements. Evaluate compatibility with existing system voltage rails and thermal management needs for the specified operating temperature range.
