Description
The Si4840/44 is the first 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 (I 2 C-compatible 2-wire control interface),
frequencies, and stereo/mono information can be displayed on LCD, while the
analog-tune features are kept. Leveraging Silicon Laboratories' proven and
patented digital low intermediate frequency (low-IF) receiver architecture, the
