RF Receivers Procurement Notes

This component is officially listed as obsolete or end-of-life by Silicon Labs. Verify availability through authorized distributors or secondary market suppliers. Confirm that the specific suffix matches required specifications. Check for environmental compliance documentation. Ensure replacement strategies are evaluated due to discontinuation status.

RF Receivers Selection Notes

Select this part for fixed-frequency OOK applications requiring moderate sensitivity. Consider the limited data rate of 10 kbps when designing system timing. Evaluate thermal requirements against the specified operating temperature range. Compare pinout compatibility if integrating into existing PCB layouts. Assess power consumption constraints relative to the 20 mA operating current.

RF Receivers Part Context

Part of the EZRadio family of single-chip RF transceivers and receivers. Designed for simple, cost-effective wireless solutions. Shares architectural similarities with other Si43xx series devices but lacks transmitter capabilities found in full transceiver variants. Targets markets needing basic remote command or sensor data transmission.
