8T49N203A-031NLGI

Overview

The Renesas Electronics Corporation 8T49N203A-031NLGI is a FemtoClock NG Universal Frequency Translator and Synthesizer. It features two differential outputs programmable as LVPECL or LVDS, supporting frequencies from 0.98MHz to 1,300MHz. The device accepts differential inputs (LVPECL, LVDS, LVHSTL, HCSL) in the 8kHz–710MHz range or a crystal input (16MHz–40MHz). It includes alarm monitoring, I²C programming, and two factory-programmable OTP configurations. Operating voltage ranges from 2.5V to 3.3V, with an ambient temperature range of -40°C to 85°C.

Feature Summary

Generates output frequencies from 0.98MHz to 1,300MHz using three modes: Frequency Synthesizer, High-Bandwidth Translator, and Low-Bandwidth Translator.
Supports two differential inputs (CLK0, CLK1) and provides two individually programmable differential outputs (Q0, Q1) selectable as LVPECL or LVDS.
Includes alarm and monitoring functions for clock validity (XTALBAD, CLK0BAD, CLK1BAD) and holdover status via dedicated pins and registers.
Configurable via I²C interface or hardware pins, featuring two factory-programmed One-Time Programmable (OTP) default configurations.

Applications

Networking and communications line cards requiring precise frequency translation.
PCI Express and computing systems utilizing high-bandwidth frequency translation.
Synchronous Ethernet applications requiring jitter attenuation and low-phase noise performance.

Procurement Notes

Verify component authenticity through authorized distributors. Confirm package integrity and moisture sensitivity level prior to assembly. Ensure compatibility with existing I²C addressing and power supply requirements during integration.

Selection Notes

Select this model for applications requiring flexible frequency synthesis from diverse input sources. Verify that the required output voltage (2.5V or 3.3V) matches the VCCO supply. Ensure the target output frequency falls within the supported divider ranges defined in the datasheet.

Part Context

This component belongs to the IDT8T49N203I FemtoClock NG family. It serves as a general-purpose clock generator suitable for replacing legacy fixed-frequency oscillators in multi-standard equipment designs.
