8T49N203A-005NLGI8

Overview

The 8T49N203A-005NLGI8 is a FemtoClock NG programmable clock generator and frequency synthesizer manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.375V to 3.465V and utilizes a 40-QFN (6x6) package with an exposed pad. The device supports frequencies up to 155.52MHz and integrates PLL and frequency synthesis circuitry for precise timing applications.

Feature Summary

• Integrates PLL and frequency synthesis circuitry for precise clock generation
• Supports operation within a 2.375V to 3.465V supply voltage range
• Utilizes a compact 40-QFN (6x6) package with an exposed pad

Applications

• General purpose clock translation
• Frequency synthesis in digital systems
• Timing reference generation for high-speed interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing lot codes against current datasheets. Ensure the 40-QFN package matches design requirements. Review official documentation for any product change notifications or end-of-life declarations prior to procurement.

Selection Notes

Select this component when a low-jitter, programmable clock solution is required for frequencies up to 155.52MHz. The 40-QFN package suits space-constrained designs. Verify that the 2.375V to 3.465V operating voltage aligns with system power rails. Consider thermal dissipation needs due to the exposed pad design in the 6x6 footprint.

Part Context

This part belongs to the FemtoClock NG family of clock generators, designed for low jitter performance. It serves as a programmable alternative to fixed-frequency oscillators, allowing designers to tailor output clocks via internal registers. The series is widely used in telecommunications and computing infrastructure requiring precise timing synchronization.

Replacement Considerations

Consult official cross-reference guides for compatible replacements. Verify pinout compatibility and electrical specifications before substituting. Check for updated packaging options or revised revision letters in newer batches.
