SI4463-C2A-GM

RF Transceiver ICS Overview

The SI4463-C2A-GM is a high-performance, low-current sub-GHz RF transceiver from Silicon Labs. It operates within the 142 MHz to 1.05 GHz frequency range and supports data rates up to 1 Mbps. The device features a maximum output power of +20 dBm and achieves receiver sensitivities as low as -129 dBm. It accepts supply voltages between 1.8 V and 3.6 V, with typical receive currents around 10.9 mA to 13.7 mA and transmit currents ranging from 44.5 mA to 88 mA. Packaged in a 20-pin QFN (4x4 mm) with an exposed pad, it functions across temperatures from -40°C to +85°C.

RF Transceiver ICS Feature Summary

• Supports FSK, GFSK, GMSK, MSK, and OOK modulation formats for versatile communication protocols.
• Integrates advanced packet processing capabilities including forward error correction and automatic frequency compensation.
• Features a flexible SPI interface for efficient control and data transfer with host microcontrollers.
• Provides configurable GPIO pins to assist in system integration and peripheral management.

RF Transceiver ICS Applications

• Wireless sensor networks
• Smart metering systems
• Industrial telemetry

RF Transceiver ICS Procurement Notes

Verify that the specific suffix 'GM' corresponds to tray packaging rather than tape-and-reel configurations when reviewing distributor listings. Confirm the revision level matches the required errata documentation, specifically checking for C2A or A2A revisions. Ensure the component meets RoHS compliance standards relevant to your target market before finalizing procurement orders.

RF Transceiver ICS Selection Notes

Select this component for applications requiring high output power and sensitivity in a compact form factor. Compare against the SI4460 series if lower transmit power requirements allow for reduced current consumption. Evaluate the need for integrated MCU capabilities versus external processing loads when designing the system architecture.

RF Transceiver ICS Part Context

This part belongs to the EZRadioPRO family of sub-GHz transceivers. It shares architectural similarities with the SI4460 and SI4461 models, differing primarily in transmit power specifications and current consumption profiles. The C2A designation indicates a specific silicon revision within the broader SI446x product line.

RF Transceiver ICS Replacement Considerations

SI4463-C2A-GMR serves as the tape-and-reel alternative offering identical electrical performance. The SI4460-C2A-GM provides a lower-power variant suitable for energy-constrained designs.
