8T49N203A-015NLGI8

Overview

The 8T49N203A-015NLGI8 is a FemtoClock NG Universal Frequency Translator IC manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.375V to 3.465V and supports an operating temperature range of -40°C to 85°C. The device features one circuit with a maximum frequency of 156.25MHz. It utilizes a 40-VFQFN package with an exposed pad, specifically a 40-QFN (6x6) configuration. The component accepts HCSL, LVDS, LVHSTL, LVPECL, or crystal inputs and provides LVPECL outputs.

Feature Summary

• Universal frequency translation capabilities for diverse clocking requirements
• Supports multiple input standards including differential and single-ended formats
• Integrated PLL functionality with bypass option for flexible design

Applications

• High-speed data handling systems
• FPGA timing and synchronization
• General-purpose clock generation in electronic equipment

Procurement Notes

This component has reached End-of-Life status and is no longer in active manufacturing. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors. Buyers must confirm that the specific suffix matches their board layout requirements, as pinouts may vary across the family. Due to the discontinued status, lead times for surplus inventory are unpredictable and subject to market availability.

Selection Notes

Engineers selecting this part should verify compatibility with existing system voltage levels, as it requires a 2.375V to 3.465V supply. The 40-VFQFN package demands appropriate PCB footprint design for thermal management. Since the device is obsolete, alternative solutions within the FemtoClock NG family should be evaluated for long-term supply chain stability and performance equivalence.

Part Context

The 8T49N203A belongs to Renesas' FemtoClock NG series, designed for low-jitter clock synthesis and translation. This specific model serves as a universal translator, bridging different clock domains in complex digital systems. It is part of a broader portfolio of timing solutions aimed at high-performance computing and communication infrastructure applications.

Replacement Considerations

The 8T49N241-994NLGI is listed as a similar replacement option by the distributor. Engineers should consult official cross-reference guides to ensure functional and pinout compatibility before substitution.
