RF Transmitter Procurement Notes

Verify the specific frequency variant required (315MHz, 434MHz, 868MHz, or 915MHz) as availability may vary by region. Confirm package integrity upon receipt. Check for obsolescence status as some variants are marked as no longer manufactured. Ensure compatibility with existing RF layout designs due to the integrated antenna structure.

RF Transmitter Selection Notes

Select this component for applications requiring a compact, cost-effective RF solution with minimal external components. The integrated antenna simplifies PCB layout but requires careful consideration of surrounding ground planes. Verify that the target market's ISM band regulations align with the specific frequency option chosen.

RF Transmitter Part Context

This part belongs to NXP's portfolio of RF transmitters targeting the Internet of Things sector. It replaces older discrete RF solutions by integrating the PLL and output stage into a single small footprint. The series supports multiple global ISM bands to facilitate worldwide product deployment.

RF Transmitter Replacement Considerations

PCF7900VHN/C0L,112 is listed as a replacement part number, though it is also noted as no longer manufactured. Verify pinout and electrical specifications against the original design requirements before substitution.
