8T49N244A-005ASGI

Overview

The 8T49N244A-005ASGI is a FemtoClock NG frequency translator IC manufactured by Renesas Electronics. It features dual PLL control and supports a maximum output frequency of 1.3 GHz with a maximum input frequency of 710 MHz. The device provides two outputs in LVPECL and LVDS formats, housed in an 80-LBGA (CABGA) package measuring 10x10 mm. It operates on supply voltages of 2.5 V and 3.3 V, with a jitter specification of 40 ps. The component functions within a temperature range of -40°C to +85°C and accepts HCSL, LVCMOS, LVDS, LVHSTL, LVPECL, and LVTTL inputs.

Feature Summary

• Dual phase-locked loop architecture for high-performance clock generation
• Supports multiple differential and single-ended input standards including LVDS and LVPECL
• Capable of generating low-jitter output signals up to 1.3 GHz
• Integrated frequency translation functionality for complex timing requirements

Applications

• Data center infrastructure clocking
• High-speed server system synchronization
• Networking equipment timing solutions

Procurement Notes

Verify the specific suffix ASGI against the latest Renesas datasheet to confirm pinout and electrical characteristics match the design requirement. Check for End-of-Life notifications or Product Change Notices as this component family has seen discontinuation notices for related variants. Confirm moisture sensitivity level handling procedures during assembly. Ensure the 80-LBGA footprint matches the PCB layout constraints.

Selection Notes

Select this component when dual PLL control is required for jitter attenuation in high-frequency applications. The 1.3 GHz output capability suits demanding data rate interfaces. Consider the 80-pin BGA package size for board space limitations. Verify compatibility with available input clock sources such as LVDS or LVPECL. Evaluate power consumption at 2.5V and 3.3V rails against system thermal budgets.

Part Context

This part belongs to the FemtoClock NG series, designed for advanced clock management. It serves as a frequency translator rather than a simple generator, allowing flexible input-to-output ratio configurations. The series targets high-reliability environments requiring precise timing integrity. Related parts in the 8T49N244 family may offer different output counts or package options.
