Si4430/31/32 RF Transceivers

The Si443x ISM band transceiver ICs are members of the EZRadioPRO® product family. While retaining all the attractive features of the earlier products such as high integration, low cost, flexibility, low BOM and easy design-in, these transceivers target more sophisticated applications and offer several enhanced parameters and features including continuous frequency coverage from 240 - 960 MHz and output power up to +20 dBm.

The ISM band transceiver ICs include built-in features such as wake-up timer, low battery detector, transmit and receive data FIFOs, power-on reset circuit and general-purpose digital I/Os. The ICs incorporate a high-performance ADC and digital modem, which perform demodulation, filtering and packet handling in the digital domain, making the ICs ideal for configuration to mutiple applications. These features simplify the system design and allow the use of cost-effective microcontrollers. The Si4432 has configurable output power from +11 to +20 dBm and is ideal for frequency hopping systems where maximum range is desired. The Si4430/31 ICs have configurable output power from -8 to +13 dBm. The Si4431 and Si4432 comply with FCC and ETSI requirements when used in any of the standard ISM Bands. A 30 MHz crystal and supply bypass capacitors are the only necessary external components, making the devices ideal for high-volume production in applications where size and cost are important.
