8T49N203A-001NLGI8

Overview

The Renesas 8T49N203A-001NLGI8 is a FemtoClock NG Universal Frequency Translator IC. It features a single PLL capable of frequency translation and jitter attenuation. The device accepts differential inputs such as LVPECL, LVDS, LVHSTL, or HCSL and provides two differential LVPECL outputs. Operating on a 2.375V to 3.465V supply, it supports I²C programming and functions within a -40°C to 85°C temperature range in a 40-VFQFN package.

Feature Summary

• Single PLL architecture for frequency translation and jitter attenuation
• Supports LVPECL, LVDS, LVHSTL, and HCSL input levels
• Two differential LVPECL output channels
• I²C programmable register interface

Applications

• SONET/SDH network equipment
• Synchronous Ethernet (SyncE) line cards
• Carrier Ethernet switches
• Test and measurement instruments

Procurement Notes

This component is identified as End-of-Life (EOL). Verification of current stock availability through authorized distributors is required. Replacement strategies should be evaluated using the manufacturer's official substitution guide due to discontinuation status.

Selection Notes

Select this part for applications requiring precise frequency translation with low jitter performance. Ensure the design accommodates the 2.375V to 3.465V supply voltage and utilizes the 40-VFQFN footprint. Verify that the required input/output signal standards match the supported LVPECL and LVDS configurations.

Part Context

Part of the FemtoClock NG family, designed for high-performance timing applications. It integrates fractional-feedback PLL technology to generate stable clock signals from various reference sources while meeting strict jitter specifications for high-speed serial interfaces.

Replacement Considerations

Consult the official Renesas order guide for verified substitutes. Potential alternatives include other models within the 8T49N203A series or the 8T49N241 series, subject to pin compatibility and electrical parameter verification.
