SiLSI4468-A2A-IM
Overview
The SI4468-A2A-IM is a high-performance, low-current wireless transceiver part of the EZRadioPRO family, designed for sub-GHz ISM band applications. It offers an exceptional output power of up to +20 dBm and a sensitivity of -133 dBm, enabling long-range communication links with a maximum data rate of 1 Mbps. Operating across a wide frequency range of 142 MHz to 1.05 GHz, this transceiver is optimized for battery-powered systems requiring reliable, low-latency connectivity.
Why Choose This Part
The SI4468 stands out for its high integration, featuring an 11-bit ADC, temperature sensor, and low battery detector within a compact 4x4 mm QFN package. It provides best-in-class sensitivity and a significant link budget of up to 153 dB, allowing for extended range without external amplifiers. Engineers benefit from extremely low power modes, including a 30 nA shutdown current and 10 mA receive current, maximizing the operational life of portable devices.
Applications
Key Specifications
Getting Started
Developers should use the Silicon Labs Wireless Development Suite (WDS) to generate configuration headers for the SPI interface. For hardware evaluation, the 4468CPCE20C915 series of pico boards can be used with the main development platform to test range and power consumption. Ensure proper matching network design for the 20 dBm output to comply with regional regulatory limits.
