RF Receivers Procurement Notes

Verify the specific ordering suffix, such as 'R2' or 'TR', to confirm tape-and-reel packaging versus tube quantities. Note that some sources indicate this product may be discontinued; check current availability status before finalizing procurement plans. Ensure RoHS compliance requirements are met if necessary, as some listings indicate non-compliance.

RF Receivers Selection Notes

Select this component for low-power UHF reception requiring minimal external RF adjustment. The SPI interface allows full configurability. Consider the 1ms wake-up time for battery-operated devices. Verify compatibility with required modulation protocols, specifically FSK or OOK, within the supported data rate limits.

RF Receivers Part Context

This part belongs to the MC335 series of PLL-tuned receivers originally developed by Freescale Semiconductor, now under NXP Semiconductors. It is functionally similar to the MC33592 but optimized for specific frequency bands. The device integrates significant RF functionality to reduce external component count.
