SI4362-C2A-GMR

RF Receivers Overview

The SI4362-C2A-GMR is a Sub-GHz RF receiver from the EZRadio® series by Silicon Labs. It operates within the 142MHz to 1.05GHz frequency range and supports FSK, GFSK, GMSK, MSK, and OOK modulation schemes. The device features a sensitivity of -126dBm and a maximum data rate of 1Mbps. It functions on a supply voltage of 1.8V to 3.6V with a receive current of 13.7mA. Packaged in a 20-QFN (4x4) surface-mount enclosure, it supports SPI interface communication and operates between -40°C and +85°C.

RF Receivers Feature Summary

• Supports multiple low-power modulation formats including FSK, GFSK, GMSK, MSK, and OOK for flexible protocol implementation.
• Delivers high sensitivity of -126dBm to ensure reliable reception in weak signal environments.
• Integrates an on-chip synthesizer and digital baseband for simplified system design and reduced external component count.

RF Receivers Applications

• Wireless sensor networks
• Remote control systems
• Industrial telemetry

RF Receivers Procurement Notes

Verify the specific suffix 'C2A' against the latest Silicon Labs datasheet revision to confirm pinout and electrical characteristics match the design requirements. Ensure the 'GMR' tape-and-reel packaging aligns with automated assembly equipment specifications. Cross-reference RoHS compliance status with current environmental regulations before finalizing procurement orders.

RF Receivers Selection Notes

Select this component when only receiving functionality is required for Sub-GHz applications. Compare against transceiver models like SI4461 if transmission capability is needed. Evaluate the 13.7mA receive current against battery life constraints. Confirm that the 20-QFN package size fits the PCB layout constraints compared to larger packages.

RF Receivers Part Context

This part belongs to the EZRadio® family of wireless receivers designed for low-cost, low-power applications. It shares the core architecture with other Si4x6x devices but lacks the transmitter section found in transceivers like the SI4460. The C2A revision indicates specific silicon errata and feature sets documented in the product selector guide.

RF Receivers Replacement Considerations

Public confirmed substitutes include SI4362-B1B-FMR, though it is marked as not recommended for new designs. Direct functional equivalents require checking the full Si4x6x product selector guide for pin-compatible or software-compatible alternatives within the EZRadio portfolio.
