8T49N203A-029NLGI

Overview

The Renesas Electronics Corporation 8T49N203A-029NLGI is a FemtoClock NG Universal Frequency Translator (UFT) and synthesizer. It generates output frequencies from 0.98MHz to 1,300MHz using two differential inputs supporting LVPECL, LVDS, LVHSTL, or HCSL levels. The device features two individually programmable LVPECL or LVDS outputs with selectable 2.5V or 3.3V levels. It operates on a 2.5V or 3.3V core supply within an ambient temperature range of -40°C to 85°C. The component utilizes fourth-generation PLL technology for low phase noise performance.

Feature Summary

Universal Frequency Translator / Synthesizer with three operating modes: Frequency Synthesizer, High-Bandwidth Translator, and Low-Bandwidth Translator.
Two differential inputs support LVPECL, LVDS, LVHSTL, and HCSL input types with a frequency range of 8kHz to 710MHz.
Two differential outputs are individually programmable as LVPECL or LVDS with selectable 2.5V or 3.3V output levels.
Includes two factory-programmed default power-up configurations stored in One-Time Programmable (OTP) memory.

Applications

Networking and communications applications requiring jitter attenuation.
PCI Express computing systems utilizing high-bandwidth frequency translation.
General purpose clock synthesis from fundamental mode crystals.

Procurement Notes

Verify the specific ordering suffix '029' against official documentation to confirm the programmed register settings. Confirm current manufacturing status as this series may be subject to discontinuation notices. Ensure compatibility with I2C programming interfaces if post-power-up reconfiguration is required.

Selection Notes

Select this component when dual independent output clocks are needed from a single reference source. Verify that the required output voltage level (2.5V or 3.3V) matches the VCCO supply requirement. Ensure the input signal type (LVPECL, LVDS, etc.) falls within the supported differential input specifications.

Part Context

This part belongs to the IDT8T49N203I FemtoClock NG family. It is a highly flexible universal frequency translator designed for low phase noise applications. The device supports zero ppm frequency translation and includes alarm monitoring functions for input references and crystal oscillators.
