RF Receivers Procurement Notes

This specific part number is listed as End of Life and Obsolete by NXP USA Inc., indicating it is no longer manufactured. Procurement efforts should focus on verifying existing stock availability through authorized distributors or secondary market suppliers. Due to its discontinued status, long-term supply stability cannot be guaranteed, and alternative sourcing strategies must be evaluated carefully before commitment.

RF Receivers Selection Notes

Engineers selecting this component should prioritize projects with defined short-term production runs due to its obsolete status. The design must account for the specific 315 MHz and 434 MHz operational frequencies inherent to this receiver variant. Compatibility with existing sub-GHz infrastructure and telemetry protocols should be validated against current system requirements to ensure seamless integration without necessitating immediate redesign.

RF Receivers Part Context

The OL2311 series belongs to NXP's portfolio of sub-1 GHz RF solutions tailored for telemetry and wireless data transmission. This receiver complements other components like the OL2300 transmitter, forming complete link solutions. It targets applications demanding reliable, low-power reception in unlicensed industrial, scientific, and medical radio bands, supporting global regulatory compliance for SRD operations.

RF Receivers Replacement Considerations

As an obsolete component, direct substitutes are not officially confirmed in public documentation. Designers should evaluate newer NXP sub-GHz receivers or multi-protocol SoCs for migration. Cross-reference with active family members or updated generation chips that support similar frequency bands and interface requirements is recommended to maintain system functionality.
