8T49N012NLGI

Overview

The 8T49N012NLGI is a clock generator and fanout distribution IC from Renesas Electronics. It operates with supply voltages of 3.3V and 2.5V, supporting LVPECL and LVCMOS output interfaces. The device provides a maximum output frequency of 312.5MHz. It is housed in a 56-pin VFQFN package with an exposed pad. This component belongs to the FemtoClock NG series, designed for high-speed data transmission applications requiring precise clock signal generation and distribution.

Feature Summary

• Frequency synthesis with programmable output frequency range
• LVPECL I/O interfaces for high-speed data transmission
• Low-power sleep mode reduces energy consumption

Applications

• High-speed data transmission systems
• Network infrastructure equipment
• Server and storage subsystems

Procurement Notes

Verify the specific ordering suffix and package variant against the official Renesas datasheet to ensure compatibility with your design requirements. Confirm that the 56-VFQFN exposed pad footprint matches your PCB layout specifications. Cross-reference the electrical characteristics, particularly the 3.3V and 2.5V supply parameters, with your system's power delivery network. Ensure compliance with RoHS standards as indicated in the product documentation before finalizing procurement.

Selection Notes

Select this component when designing systems requiring LVPECL or LVCMOS outputs at frequencies up to 312.5MHz. Consider the 56-VFQFN package for space-constrained layouts. Evaluate the low-power sleep mode feature if energy efficiency during idle states is a critical design parameter. Compare against other FemtoClock NG variants based on specific pinout and interface requirements.

Part Context

This part belongs to the Renesas FemtoClock NG family of clock generators. These devices are engineered for jitter attenuation and clock distribution in demanding digital environments. The 8T49N012NLGI specifically targets applications needing reliable clock signals with LVPECL/LVCMOS compatibility, distinguishing it from pure buffer or oscillator components within the broader clock support portfolio.

Replacement Considerations

Consult the official cross-reference list for direct substitutes. Verify pin-to-pin compatibility and electrical equivalence before replacement.
