• Field Programmable Gate Array (FPGA) timing infrastructure
• Space-constrained electronic designs needing compact clock solutions

Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Renesas Electronics Corporation. Procurement must focus on identifying verified substitute part numbers rather than sourcing the original model. Buyers should confirm availability through authorized distributors or secondary markets while ensuring compatibility with replacement devices. Verify that any alternative components meet the same electrical specifications and package requirements to maintain system integrity.

Selection Notes

Engineers selecting this component should note its discontinued status and prioritize functional equivalents. The FemtoClock NG series offers advanced jitter performance suitable for sensitive digital interfaces. When evaluating alternatives, ensure the replacement supports the required 3:2 ratio and compatible I/O standards. Consider thermal management and board space constraints, as the VFQFN package requires specific layout guidelines for optimal performance and reliability in high-speed applications.

Part Context

The 8T49N203A belongs to the FemtoClock NG family, designed for low-jitter clock generation and distribution. This specific model serves as a universal translator, bridging different clock domains in complex electronic systems. Its development reflects Renesas's focus on providing flexible timing solutions for high-performance computing and communication equipment where signal integrity is critical.

Replacement Considerations

The 8T49N241-994NLGI is a confirmed similar substitute part number available for this obsolete component. Engineers should verify pinout compatibility and electrical parameters before implementation.
