8T49N244A-000ASGI

Overview

The Renesas 8T49N244A-000ASGI is a dual-phase-locked loop (PLL) clock translator within the FemtoClock NG family. It supports a maximum output frequency of 1.3 GHz and accepts input frequencies up to 710 MHz. The device provides two outputs in LVPECL or LVDS formats, housed in an 80-pin CABGA package. Operating temperatures range from -40°C to +85°C with supply voltages of 2.5V or 3.3V. This specific configuration utilizes Low Bandwidth mode with manual pin-based switchover.

Feature Summary

• Dual PLL architecture for independent frequency translation
• Maximum output frequency of 1.3 GHz
• Supports LVPECL and LVDS output styles
• Manual pin-controlled switchover mechanism

Applications

• Networking equipment requiring precise clock distribution
• Telecommunication infrastructure systems
• High-speed data transmission interfaces

Procurement Notes

Verify component authenticity through authorized distributors. Confirm that the ordering suffix matches the required electrical configuration. Check for moisture sensitivity handling requirements during storage and assembly. Ensure compatibility with existing PCB layouts for the 80-CABGA package.

Selection Notes

Select this model when dual independent PLLs are necessary for separate clock domains. Verify that the 1.3 GHz maximum frequency meets system requirements. Consider the manual pin switchover feature if hardware-level control is preferred over I2C programming for mode selection.

Part Context

This component belongs to the 8T49N244I series, designed as a Universal Frequency Translator. It integrates low-phase noise synthesis capabilities suitable for demanding networking applications. The FemtoClock NG technology ensures high performance in jitter attenuation and frequency generation tasks.

Replacement Considerations

Consult official documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications before implementation.
