Si4827/40/44 Analog-Tuned Digital Display AM/FM/SW Radio Receiver
Si4827/40/44 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 MCU compatible 2-wire control interface, frequencies and stereo/mono information can be displayed on an LCD, while analog-tune features are kept intact.
Built on our proven and patented digital low intermediate frequency (low-IF) receiver architecture, Si4827/40/44 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. For consumer applications requiring EN 55020 compliance, use Si4840/44 devices.
