8T49N008A-056NLGI

Overview

The 8T49N008A-056NLGI is a programmable clock generator from the FemtoClock NG series by Renesas Electronics. It features one PLL and eight LVPECL/LVDS outputs, supporting frequencies up to 312.5MHz. The device operates on a 2.375V to 3.465V supply within a -40°C to +85°C temperature range. Packaged in a 32-VFQFN with an exposed pad, it accepts crystal inputs and provides differential outputs for low-jitter signal generation in high-speed digital systems.

Feature Summary

• Eight-output configuration with LVPECL or LVDS levels
• Maximum output frequency of 312.5MHz
• Single PLL architecture with crystal input
• 32-VFQFN package (5x5mm) with exposed pad

Applications

• High-speed data communication equipment
• Network infrastructure timing solutions
• Test and measurement instrumentation

Procurement Notes

This component is listed as discontinued by the manufacturer. Verification of end-of-life status and last-time buy availability is required before procurement planning. Supply chain constraints may apply due to the obsolescence notification.

Selection Notes

Select this part for applications requiring eight differential outputs at frequencies up to 312.5MHz. Ensure compatibility with the 32-VFQFN footprint and verify that the 2.375V-3.465V supply voltage aligns with system power rails. Consider the discontinued status when designing for long-term production.

Part Context

Part of the FemtoClock NG family, designed for jitter attenuation and frequency synthesis. The 8T49N008A variant specifically targets multi-output clock distribution needs in networking and telecom sectors, offering precise timing control through register programming.

Replacement Considerations

Due to discontinuation, evaluate alternative clock generators from the same family or newer generations. Verify pinout compatibility and electrical specifications such as output drive strength and supply voltage ranges before substitution.
