The Si4840 and Si4844 from Silicon Labs are the first CMOS AM/FM/SW radio receiver ICs with analogue tuning and digital display that integrate the complete receiver function from antenna input to audio output. Based on Silicon Labs’ proven and patented digital low intermediate frequency receiver architecture, the Si4840 and Si4844 deliver superior RF performance and interference rejection. The integrated control algorithm provides an easy and reliable control interface while eliminating all of the manually tuned external components used in a traditional receiver. [via]
