SI4362-B0B-FM

RF Receivers Overview

The SI4362-B0B-FM is a high-performance, low-current RF receiver from Silicon Labs' EZRadioPRO series. It operates in the sub-GHz frequency bands ranging from 142 MHz to 1.05 GHz. The device supports multiple modulation schemes including FSK, GFSK, MSK, ASK, and OOK. Key electrical parameters include a receive current of 13 mA, a maximum data rate of 1 Mbps, and a sensitivity of -126 dBm. It functions within a supply voltage range of 1.8 V to 3.6 V and operates at temperatures between -40°C and +85°C. The component is housed in a 20-VFQFN package with exposed pad.

RF Receivers Feature Summary

• Supports FSK, GFSK, MSK, ASK, and OOK modulation protocols for versatile wireless communication.
• Features high sensitivity of -126 dBm for reliable long-range reception.
• Integrates an on-chip crystal oscillator for simplified design.
• Utilizes SPI interface for configuration and control.

RF Receivers Applications

• Garage and gate openers
• Wireless sensors
• Remote keyless entry systems

RF Receivers Procurement Notes

Verify the specific suffix B0B against the manufacturer's official product selector guide to confirm availability and exact specifications. Check for any errata or PCN updates related to the B0B revision. Ensure the procurement source provides valid RoHS compliance documentation. Confirm that the 20-QFN package dimensions match the target PCB footprint requirements before finalizing orders.

RF Receivers Selection Notes

Select this component when a dedicated receiver solution is required for sub-GHz applications. Compare against the SI4362-C2A variant if newer design-in support is needed, as the B0B may be designated for existing designs. Evaluate power consumption requirements against the 13 mA receive current. Consider the -126 dBm sensitivity for link budget calculations in noisy environments.

RF Receivers Part Context

The SI4362-B0B-FM belongs to the EZRadioPRO family of single-chip receivers. It is part of the broader SI4362 series, which includes variants like the C2A. This specific part number indicates the B0B silicon revision packaged in tape and reel format. It serves as a cost-effective alternative to transceivers when transmission capability is not required.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult the official Silicon Labs product selector guide for direct replacements or pin-compatible alternatives within the EZRadioPRO family.
