“The idea of a single chip radio is intriguing. The prospect is especially interesting to me because, frankly, I envy the analog skills I associate with building a radio receiver. When I browsed the circuit literature in the area, I …

Si4844-A10-GU4 devices are the first analog-tuned digital-display CMOS AM/FM/SW radio receiver ICs that integrate the complete receiver function from antenna input to audio output. Working with a host microcontroller (MCU) compatible 2-wire control interface, frequencies and stereo/mono information can be displayed on an LCD, while the analog-tune features are kept intact. Built on our patented digital low intermediate frequency (low-IF) receiver architecture, Si4844-A10-GU ICs deliver superior RF performance and interference rejection. The integrated superior control algorithm provides an easy and reliable control interface while eliminating all of the manual tuned external components used in a traditional solution.
