The Silicon Labs SI4421-A1-FTR is a single-chip, low-power, multi-channel FSK transceiver. It is designed for applications requiring FCC or ETSI conformance in the 433, 868, and 915 MHz bands. This transceiver is part of Silicon Labs' EZRadio product line, offering a flexible, low-cost, and highly integrated solution.
Key electrical specifications include an operating frequency range of 315MHz, 434MHz, 868MHz, and 915MHz, with FSK modulation. It supports a maximum data rate of 256kbps and features a sensitivity of -110dBm with an output power of 7dBm. The device operates within a voltage range of 2.2V to 3.8V and consumes between 11mA and 13mA of current.
The SI4421-A1-FTR operates within an industrial temperature range of -40°C to 85°C. It is housed in a 16-TSSOP package and is designed for surface mount applications. The integrated PLL synthesizer and digital data processing features reduce the load on the microcontroller, simplifying RF design and reducing the Bill of Materials (BOM).
This transceiver is suitable for various wireless applications requiring reliable communication in unlicensed ISM bands. Its integrated design and ease of use make it a compelling choice for designers looking for a robust and cost-effective RF solution.
