Si4432/31/30 ISM Transceiver Features - Frequency Range = 240–930 900–960 MHz (Si4432/31) MHz (Si4430) dBm = –118 - Sensitivity - FSK, GFSK, and OOK modulation - Max Output Power = +20 +13 - Low Power Consumption mA receive - 18.5 - 27 mA @ +11 dBm transmit dBm (Si4432) dBm (Si4431/30) Description Silicon Laboratories’ Si4432/31/30 highly-integrated, single chip wireless ISM transceiver is part of the EZRadioPRO™ family. The EZRadioPRO family includes a complete line of transmitters, receivers, and transceivers allowing the RF system designer to choose the optimal wireless part for their application. including features, radio The Si4432/31 offers advanced from 240–930 MHz and continuous frequency coverage dBm with the Si4432. The adjustable output power of up to +20 Si4430 offers frequency coverage from 900 to 960 MHz to support the Japanese frequency bands. The Si4432/31/30’s high level of integration offers reduced BOM cost while simplifying overall system design. The extremely low receive sensitivity (–118 dBm) coupled with the Si4432’s industry-leading +20 dBm output power ensures extended range and improved link performance. Built-in antenna diversity and support for frequency hopping can be used to further extend range and enhance performance. Antenna diversity is completely integrated into the Si443x and can improve the system link budget by 8–10 dB, resulting in substantial range increases under adverse environmental conditions. Additional system features, such as an automatic wake-up timer, byte TX/RX FIFOs, automatic packet low battery detector, 64 handling, and preamble detection, reduce overall current consumption and allow the use of lower-cost system MCUs. An integrated temperature sensor, general-purpose ADC, power-on- reset (POR), and GPIOs further reduce overall system cost and size. The Si4432/31/30 receiver uses a single-conversion architecture to convert the 2-level FSK/GFSK/OOK modulated receive signal to a low IF frequency. Following a programmable gain amplifier (PGA) the signal is converted to the digital domain by a high- performance delta-sigma ADC allowing filtering, demodulation, slicing, error correction, and packet handling to be performed in the built-in DSP, increasing the receiver’s performance and flexibility versus analog based architectures. The PA is single-ended to allow for easy antenna matching and low BOM cost. The digital transmit modulation and automatic PA power ramping ensure precise transmit modulation and reduced spectral splatter, ensuring compliance with FCC and ETSI regulations. The Si4430 is designed to ensure compliance with ARIB regulations. The Si4432/31/30 is designed to work with an MCU, crystal, and a few passives to create a very low-cost system. Voltage regulators are integrated on-chip, which allows for a wide range of operating supply voltage conditions from +1.8 to +3.6 V.
