SI4312-B10-GMR

RF Receivers Overview

The SI4312-B10-GMR is a Sub-GHz RF receiver from the EZRadio series, designed for OOK modulation at 315 MHz and 433.92 MHz. It operates on a supply voltage of 2.7 V to 3.6 V with a typical current consumption of 20 mA during reception. The device features high sensitivity of -110 dBm and supports data rates up to 10 kbps. Packaged in a compact 20-QFN (3x3 mm) surface-mount format, it functions within a temperature range of -40°C to +85°C.

RF Receivers Procurement Notes

This component is officially classified as obsolete by Silicon Labs. Verify end-of-life status and request final time buy information directly from authorized distributors or the manufacturer before design finalization. Ensure all procurement activities account for potential supply chain discontinuation risks associated with legacy parts.

RF Receivers Selection Notes

Select this part only if legacy compatibility with existing 315 MHz or 433.92 MHz OOK infrastructure is required. Evaluate alternative active EZRadio models for new designs due to the obsolete status. Confirm that the 10 kbps maximum data rate meets application latency requirements and that the 20 mA receive current fits power budget constraints.

RF Receivers Part Context

Part of the EZRadio family, the SI4312-B10-GMR serves as a specialized receiver for low-data-rate wireless applications. It complements transmitter counterparts in complete wireless links. The specific B10 suffix denotes frequency band and package configuration within the broader Si431x product line, targeting cost-sensitive industrial and consumer markets.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the part is obsolete, engineers must identify pin-compatible or functionally equivalent active receivers from the same manufacturer or competitors through independent technical cross-reference analysis.
