Procurement Notes

Verify the exact order code suffix against the official datasheet to ensure correct factory pre-programming. Confirm package type and moisture sensitivity level requirements for your assembly process. Check for any Product Change Notices (PCN) related to marking or material changes. Ensure compatibility with your I2C interface voltage levels. Validate RoHS compliance status for your specific region regulations.

Selection Notes

Select this part when a fixed-frequency configuration from the 8T49N1012 family is required. Compare output drive strength and format options against system requirements. Consider the operating temperature range and supply voltage specifications. Evaluate the need for internal crystal oscillator versus external reference input. Review register settings for specific jitter performance targets.

Part Context

This component is part of the Renesas FemtoClock NG family, known for advanced PLL technology. It serves as a clock synthesizer for high-performance digital systems. The 8T49N1012 series offers flexible output configurations. It is distinct from other series like the 8T49N203A or 8T49N240 in terms of output count and specific jitter characteristics.

Replacement Considerations

Consult the official Renesas replacement guide for verified substitutes. Generic cross-references may not match the specific factory pre-programmed settings. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
