SI4460-C2A-GM

RF Transceiver ICS Overview

The SI4460-C2A-GM is a sub-GHz RF transceiver IC from Silicon Labs, operating within the 142 MHz to 1.05 GHz frequency range. It supports data rates up to 1 Mbps with modulation formats including FSK, GFSK, GMSK, MSK, and OOK. The device features a maximum output power of +13 dBm and receiver sensitivity ranging from -126 dBm to -129 dBm. It operates on a supply voltage of 1.8 V to 3.6 V, with receive current consumption between 10.9 mA and 13.7 mA, and transmit current between 18 mA and 29 mA. Communication is managed via an SPI interface, and it is housed in a 20-QFN (4x4 mm) package.

RF Transceiver ICS Feature Summary

• Supports multiple modulation schemes including FSK, GFSK, GMSK, MSK, and OOK for versatile wireless communication.
• Designed for low-power operation, enabling single coin cell functionality with optimized current consumption.
• Integrates a high-performance transmitter and receiver with configurable output power levels.

RF Transceiver ICS Applications

• Wireless sensor networks
• Industrial control systems
• Smart metering applications

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'GM' against the manufacturer's official documentation to confirm the tray packaging configuration, as other suffixes like 'GMR' indicate tape-and-reel options. Ensure the revision code 'C2A' matches the required hardware errata level for your design. Cross-reference the datasheet version date to confirm compliance with current regulatory standards and pinout definitions before finalizing procurement.

RF Transceiver ICS Selection Notes

Select this component when a sub-GHz ISM band transceiver with integrated MCU support capabilities is required. It is suitable for designs prioritizing low current consumption during transmission while maintaining high sensitivity. Consider the 20-QFN package size constraints and SPI interface requirements. Compare against the SI4460-B1B variant if different manufacturing sites or legacy compatibility are needed, noting potential differences in recommended usage status.

RF Transceiver ICS Part Context

The SI4460 belongs to the EZRadioPRO family of highly integrated transceivers. This specific model represents a revision within the Si446x series, offering enhanced performance over previous generations. It is part of a broader ecosystem that includes companion parts like the SI4463 and SI4461, which share similar architectural foundations but may differ in specific feature sets or regional availability.

RF Transceiver ICS Replacement Considerations

The SI4460-B1B-FMR is a related part number within the same product family, though it may carry a Not Recommended for New Design (NRND) status. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Consult the latest Silicon Labs selection guide for any newer revisions that might offer improved supply chain stability or updated specifications.
