8T49N203A-031NLGI8

Overview

The Renesas 8T49N203A-031NLGI8 is a FemtoClock NG Universal Frequency Translator and Synthesizer. It generates output frequencies from 0.98MHz to 1,300MHz using two differential inputs (LVPECL, LVDS, LVHSTL, HCSL) or a crystal source. The device features two individually programmable LVPECL/LVDS outputs with 2.5V or 3.3V levels. It supports three modes: Frequency Synthesizer, High-Bandwidth Translator, and Low-Bandwidth Translator for jitter attenuation. Power supply ranges from 2.375V to 3.465V. It includes alarm monitoring, I2C configuration, and two factory-programmable OTP configurations.

Feature Summary

Universal Frequency Translator supporting 0.98MHz to 1,300MHz output range
Three operating modes: Synthesizer, High-Bandwidth, and Low-Bandwidth Frequency Translation
Two differential inputs (CLK0/CLK1) and two differential outputs (Q0/Q1)
Factory-programmable One-Time Programmable (OTP) memory for two default configurations

Applications

Networking and communications equipment requiring clock translation
PCI Express and computing systems utilizing high-bandwidth frequency translation
General purpose applications needing flexible frequency synthesis from crystal sources

Procurement Notes

Verify component authenticity through authorized distributors. Confirm the specific ordering suffix matches required package and temperature specifications. Check for End-of-Life (EOL) status and lead times as availability may be limited. Ensure I2C address pins are configured correctly for system integration.

Selection Notes

Select this model when dual differential outputs with independent LVPECL/LVDS programming are required. Choose based on input frequency range (8kHz-710MHz) and desired jitter performance in low-bandwidth mode. Verify that the 40-VFQFN package fits the PCB layout constraints. Consider the need for factory-programmed OTP configurations versus post-power-up I2C reconfiguration.

Part Context

This component belongs to the IDT/Renesas FemtoClock NG family of universal frequency translators. It succeeds earlier generations by offering enhanced flexibility with fractional feedback division and dual configurable outputs. The part integrates alarm monitoring and holdover capabilities suitable for robust network synchronization applications.

Replacement Considerations

Public confirmed substitute part numbers include 8T49N241-994NLGI, 8T49N241-998NLGI, and 8T49N241-999NLGI. These alternatives offer similar clock generation capabilities but may differ in specific output counts or packaging details.
