8T49N203A-028NLGI

Overview

The Renesas Electronics Corporation 8T49N203A-028NLGI 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 (16MHz - 40MHz). The device features two individually programmable LVPECL or LVDS outputs with 2.5V or 3.3V levels. It supports three operating modes: Frequency Synthesizer, High-Bandwidth Frequency Translator, and Low-Bandwidth Frequency Translator. Power supply ranges are 2.375V to 3.465V for VCC/VCCA and VCCO. Operating temperature is -40°C to 85°C in a 40-VFQFN package.

Feature Summary

Fourth-generation FemtoClock NG technology with zero ppm frequency translation capability
Two differential inputs supporting LVPECL, LVDS, LVHSTL, and HCSL signals within an 8kHz - 710MHz range
Two factory-set register configurations stored in One-Time Programmable ROM for power-up defaults
I2C serial interface for post-power-up register programming and configuration overwriting

Applications

Networking and communications line cards requiring alarm and monitoring functions
PCI Express and computing applications utilizing high-bandwidth frequency translation
General purpose clock generation where independent input/output frequency relationships are required

Procurement Notes

Verify component authenticity through authorized distributors. Confirm the specific ordering suffix matches the required voltage and package specifications. Check for End-of-Life status as this series may be discontinued. Ensure I2C address pins align with system bus requirements before procurement.

Selection Notes

Select based on required output frequency range and input signal type compatibility. Choose between low-bandwidth mode for jitter attenuation or high-bandwidth mode for spread-spectrum tracking. Verify that the desired output voltage level (2.5V or 3.3V) matches the target load requirements. Ensure the I2C slave address configuration fits the available bus addresses.

Part Context

This component belongs to the IDT8T49N203I FemtoClock NG family. It serves as a flexible frequency translator capable of generating arbitrary output frequencies from various input sources without integer relationship constraints. The device integrates alarm monitoring for input clocks and crystals, enhancing reliability in critical timing applications.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the verified local source material. Consult manufacturer documentation for current replacement options if this part is obsolete.
