Description
Modules for consumer electronics
Toys, lamps, and any application
needing an AM/FM/SW radio
The Si4827 is an 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. The Si4827 enhances the FM and SW band coverage, and further
supports China TV channels audio reception in FM band. The superior control
algorithm integrated in the Si4827 provides an easy and reliable control interface
while eliminating all the manual tuned external components used in traditional
solutions.
