Introduction

The Si4822/26 is the entry level analog-tuned digital-display digital CMOS AM/FM/SW radio receiver IC that integrates the complete receiver function from antenna input to audio output. Working with Host MCU (I²C-compatible 2-wire control interface), frequencies information can be displayed on LCD, while the analog-tune features are kept. Leveraging Skyworks' proven and patented digital low intermediate frequency (low-IF) receiver architecture, the Si4822/26 delivers superior RF performance and interference rejection. The superior control algorithm integrated in Si4822/26 provides easy and reliable control interface while eliminating all the manual tuned external components used in traditional solutions.
