8T49N008A-046NLGI

Overview

The 8T49N008A-046NLGI is a clock buffer integrated circuit manufactured by Renesas Electronics Corporation. It features one input and eight outputs, supporting LVPECL signaling. The device operates with a maximum frequency of 1.25 GHz and accepts crystal inputs. It is housed in a surface-mountable 40-QFN package and is designed for operation across an extended temperature range of -40°C to +85°C.

Feature Summary

• Supports eight selectable LVPECL or LVDS outputs
• Utilizes fourth-generation FemtoClock NG PLL technology
• Accepts CLK and nCLK input pairs

Applications

• High-speed data transmission systems
• Telecommunications infrastructure
• Server and storage backplanes

Procurement Notes

Verify the specific suffix code against official Renesas documentation to confirm exact output configuration and electrical characteristics. Ensure compatibility with system voltage requirements and thermal management specifications before integration. Cross-reference the part number with current product lifecycle status to confirm availability and long-term supply stability.

Selection Notes

Select this component when a single differential input must be distributed to multiple high-speed logic families requiring LVPECL signaling. Consider the 40-QFN package for space-constrained designs. Verify that the 1.25 GHz maximum frequency meets the target application's timing requirements and that the operating temperature range aligns with environmental conditions.

Part Context

This part belongs to the FemtoClock NG family, which integrates advanced PLL technology for low-jitter clock generation and distribution. The 8T49N series provides flexible output configurations, allowing designers to choose between LVPECL and LVDS standards. This specific model focuses on buffering and distributing reference clocks to multiple downstream components in complex digital systems.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify pinout compatibility and electrical parameter equivalence before replacing.
