8T49N203A-003NLGI

Overview

The 8T49N203A-003NLGI is a Universal Frequency Translator (UFT) from the FemtoClock NG family, manufactured by Renesas Electronics Corporation. It features a single PLL capable of frequency translation and jitter attenuation. The device accepts differential inputs such as LVPECL, LVDS, LVHSTL, HCSL, or crystals. It provides two differential LVPECL outputs with a maximum frequency of 25MHz. Operating voltages range from 2.375V to 3.465V, and it functions within an ambient temperature range of -40°C to +85°C in a 40-VFQFN package.

Feature Summary

• Supports universal frequency translation with independent output frequencies relative to input references
• Integrates jitter attenuation capabilities for signal integrity improvement
• Configurable via I2C interface for flexible register programming

Applications

• SONET/SDH network line cards
• Ethernet network synchronization equipment
• Wireless base station baseband units

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS3 compliance status. Check for Product Change Notices regarding assembly site or marking modifications. Validate moisture sensitivity level handling requirements during storage and reflow soldering processes.

Selection Notes

Select this model when requiring a compact clock translator with dual differential outputs. Ensure input signal levels match supported standards like LVPECL or LVDS. Verify that the 25MHz maximum output frequency meets system timing requirements. Consider thermal management for the VFQFN package in enclosed environments.

Part Context

This component belongs to the FemtoClock NG series, designed for high-performance timing applications. It serves as a successor to earlier IDT frequency translators, offering enhanced jitter performance and flexible configuration options for modern communication infrastructure.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pinout compatibility and electrical specifications before replacing. Ensure new components meet identical environmental and regulatory standards.
