8T49N008A-048NLGI

Overview

The 8T49N008A-048NLGI is a programmable clock generator from the FemtoClock NG series, manufactured by Renesas Electronics Corporation. It features one input and eight outputs with a maximum frequency of 300 MHz. The device supports differential inputs including HCSL, LVDS, and LVPECL, while providing LVPECL or LVDS output options. It operates on a single supply voltage ranging from 2.375 V to 3.465 V within an industrial temperature range of -40°C to +85°C. The component is housed in a 40-VFQFN exposed pad package and includes an integrated PLL with bypass functionality.

Feature Summary

• Eight-output configuration supporting LVPECL or LVDS signal standards
• Integrated PLL with bypass capability for flexible clock routing
• Supports multiple input formats: HCSL, LVDS, and LVPECL
• Operates within a 2.375 V to 3.465 V supply range

Applications

• High-speed data communication systems requiring low-jitter clocking
• Networking equipment utilizing FemtoClock NG jitter attenuation
• Industrial control systems operating in extended temperature environments

Procurement Notes

This component is listed as discontinued by the manufacturer. Verification of end-of-life status and final purchase dates is required before procurement planning. Availability is limited to existing stock or last-time buy opportunities through authorized distributors. Confirm RoHS3 compliance and moisture sensitivity level (MSL 3) during sourcing.

Selection Notes

Select this part when eight synchronized outputs are required from a single clock source. Ensure the design accommodates the 32-VFQFN or 40-VFQFN package footprint depending on the specific suffix variant. Verify that the input signal matches supported formats such as LVDS or LVPECL. Check for alternative active components if long-term supply continuity is critical.

Part Context

The 8T49N008A belongs to the FemtoClock NG family, designed for high-performance clock generation and jitter cleaning. This series is widely used in telecommunications and computing infrastructure where precise timing is essential. The 'A' suffix typically denotes a specific revision or feature set within the 8T49N008 base product line.

Replacement Considerations

As the 8T49N008A-048NLGI is discontinued, verify pin-compatible alternatives within the same FemtoClock NG family. Consult official replacement guides for updated part numbers that maintain electrical compatibility and package dimensions.
