SI4362-C2A-GM - 1.05GHz RF Receiver | Silicon Labs
部品番号: SI4362-C2A-GM ✓ 生産中SI4362-C2A-GM 概要
An RF receiver is the front end of a wireless communication system that converts a modulated radio-frequency signal into a digital data stream. In the signal-chain hierarchy, the SI4362-C2A-GM belongs to the sub-GHz radio category, integrates RF receiver functionality, and is intended for use beneath a system-level wireless link. Its combination of multiple modulation formats and a wide frequency range allows one receiver design to serve metering, remote-control, industrial telemetry, consumer accessory, and connected-product applications.
Key verified features include a 142 MHz to approximately 1.05 GHz operating range, FSK, GFSK, GMSK, MSK, and OOK support, a stated 1 Mbps data rate, and -126 dBm receiver sensitivity in the distributor specification. The device operates from 3.3 V and is offered in a 4 x 4 mm 20-pin QFN package with exposed pad. These characteristics support compact, low-power receiver modules where board area, radio sensitivity, and modulation flexibility are important.
The SI4362 belongs to Silicon Labs' EZRadioPRO family of sub-GHz radio devices. Its receiver architecture is configured through device registers and firmware, allowing a host processor to select channel-related operating parameters and modulation behavior. Because the supplied sources do not expose the complete electrical characteristics table or register map, values for current consumption, data-rate limits by modulation, crystal requirements, and detailed sensitivity-versus-data-rate behavior remain datasheet-dependent rather than being inferred here.
Typical uses include low-power wireless telemetry, smart-home accessories, industrial remote controls, consumer device links, and IoT-connected products operating below 1.05 GHz. In these systems, the receiver can process FSK or OOK signals from inexpensive transmitters, while higher-order modulation options support designs where data efficiency and link robustness are more important. The exposed-pad QFN construction also requires careful PCB thermal and RF layout implementation.
The primary design consideration is RF implementation: keep the antenna path controlled, place decoupling close to the supply pins, follow the manufacturer's reference layout, and preserve the exposed-pad thermal and ground requirements. Firmware configuration must also match the transmitter's modulation, channel, symbol rate, packet format, and frequency-error tolerance; otherwise, nominal hardware sensitivity does not guarantee a reliable link.
This product record combines verified distributor specifications, official Silicon Labs datasheet information, package and sourcing details, and application-oriented engineering guidance. It also clearly separates published facts from unavailable parameters, helping engineers identify what must be confirmed in the manufacturer datasheet before schematic release, PCB layout, or production sourcing.

主な用途
SI4362-C2A-GM の用途: 6 件s: Industrial Wireless Telemetry, Smart-Home and IoT Accessories, Remote Controls and Consumer Accessories, Wireless Sensor and Metering Networks, RF Test and Measurement Equipment, Robotics and Equipment-Control Links.
Industrial Wireless Telemetry
The SI4362-C2A-GM is suitable for sub-GHz industrial telemetry links that must tolerate a broad range of frequency plans. Its receiver covers 142 MHz to approximately 1.05 GHz and supports FSK, GFSK, GMSK, MSK, and OOK, allowing the same hardware platform to accept several common remote-sensor protocols. The verified 1 Mbps capability is useful when sensor packets, acknowledgment messages, or configuration updates cannot be sent slowly. In a meter-reading or equipment-monitoring design, the receiver converts the modulated RF signal into a digital stream for a host MCU. Implementation should follow the Silicon Labs reference layout, preserve the exposed-pad ground path, and verify channel spacing and frequency-error tolerance for the selected modulation.
おすすめ
Smart-Home and IoT Accessories
The SI4362-C2A-GM fits smart-home and IoT accessory links that combine modest data rates with multiple modulation choices. OOK supports simple low-cost transmitters, while FSK and GFSK provide alternatives for more robust links; GMSK and MSK are available when modulation efficiency matters. The device's 142 MHz-to-approximately-1.05-GHz range also allows designers to select an appropriate regional sub-GHz channel plan. A typical design places the receiver beside a low-power host MCU and connects it through a serial control interface. Because many battery-operated nodes spend substantial time idle, verify the actual receive and standby current in the manufacturer datasheet before estimating the complete link's service interval.
おすすめ
Remote Controls and Consumer Accessories
The SI4362-C2A-GM can support remote-control and consumer-accessory receivers where commands are transmitted through OOK or FSK-style links. OOK remains useful for simple buttons and low-rate command traffic, while FSK and GFSK can improve resilience against amplitude variation and interference. With verified operation up to 1 Mbps, the receiver can also handle larger device-pairing or firmware-transfer messages when the link budget permits. The 4 x 4 mm, 20-pin QFN package helps reduce board area in compact products. Designers should still account for the exposed pad, antenna clearance, regulatory constraints, and the receiver's startup behavior rather than treating the compact package as a complete RF solution.
おすすめ
Wireless Sensor and Metering Networks
The SI4362-C2A-GM is appropriate for wireless sensor and metering networks that periodically receive short packets from distributed endpoints. FSK and GFSK support can accommodate simple low-cost sensor transmitters, while the receiver's verified 1 Mbps capability provides headroom for larger telemetry frames or acknowledgments. A host controller can configure the channel and modulation through the radio interface, then forward validated measurements over a wired network. For installation sites with poor propagation, engineers should use the published sensitivity under the intended modulation and data-rate conditions and add antenna diversity if necessary. The 3.3 V device must be paired with a regulator and bypass network designed according to the manufacturer guidance.
おすすめ
RF Test and Measurement Equipment
The SI4362-C2A-GM can serve as the receiving element in compact RF test equipment, wireless data loggers, or communication demonstrators. Its broad tuning range allows one receiver design to cover multiple sub-GHz test frequencies, while FSK, GFSK, GMSK, MSK, and OOK support enables testing of multiple modulation types without changing the hardware footprint. At the verified maximum stated data rate of 1 Mbps, it can support high-throughput test traffic where link conditions permit. The receiver should be combined with a calibrated reference source, controlled attenuation, and careful RF partitioning. Development boards and companion controllers should follow the Silicon Labs reference design to minimize unintended sensitivity loss and interference.
おすすめ
Robotics and Equipment-Control Links
The SI4362-C2A-GM is useful for command and status links in robotics, industrial equipment, and mobile control accessories. The receiver supports several modulation formats, allowing compatibility with low-cost OOK transmitters or more robust FSK/GFSK control links. A 1 Mbps data rate can shorten the time needed to exchange position, diagnostic, or configuration data compared with a lower-rate link, although actual throughput remains dependent on packet overhead and link margin. In a mobile environment, antenna placement and multipath behavior may be more important than nominal sensitivity. Designers should test the complete enclosure, antenna, and power system, keep the QFN exposed pad thermally and electrically compliant, and provide firmware configuration suitable for robust packet filtering and acknowledgments.

設計ノート
Use the official Silicon Labs Si4362-C reference layout for the 20-pin QFN footprint and exposed pad. Place the required supply bypass capacitors adjacent to the relevant power and ground pins, connect the exposed pad to the prescribed ground structure, and maintain the manufacturer-defined solder-mask and land-pattern geometry. Do not copy a generic 20-QFN footprint without checking the exposed-pad dimensions because thermal and RF performance can be affected by the final copper and assembly process.
Keep the antenna connection, matching network, and receiver input path short and isolated from switching supplies, digital clocks, and high-current return paths. Route the radio interface and control signals away from the sensitive RF input, and use a solid ground reference under the device. The supplied excerpts do not specify matching values or crystal topology, so those details must come from the manufacturer datasheet and application guidance rather than general RF assumptions.
A common integration error is selecting the radio frequency, modulation type, symbol rate, and packet structure independently on the transmitter and receiver. The SI4362-C2A-GM supports FSK, GFSK, GMSK, MSK, and OOK, but each mode has different bandwidth and link-budget behavior. Before production testing, reproduce the intended transmitter configuration and verify channel spacing, frequency error, preamble, synchronization word, and packet filtering using the manufacturer's recommended setup.
Design the 3.3 V rail for the receiver's active, standby, and startup states using the current values published in the Silicon Labs Si4362-C datasheet. The excerpts identify the device as a low-current receiver but do not provide those numerical limits. Estimate battery life from measured duty cycle rather than assuming continuous receive consumption, and provide local decoupling close to the device so radio performance is not affected by supply ripple or shared converter switching transients.
