Silicon Laboratories’ new Si4830 is an AM/FM receiver IC designed for a wide range of radio products such as portable radios, boom boxes, clock and lamp radios, toy radios and give-away radios.
The chip is a CMOS wheel-tuned AM/FM radio receiver IC, offering a full AM/FM radio from antenna input to audio output in a single small chip. Its high level of integration reduces component count significantly, since it eliminates the need for external microcontrollers, AM/FM filters, tuning inductors and other components. Developers need only add an antenna, mechanical tuning and off/on volume wheels, amplification and two AAA batteries.
The IC supports European EN55020 compliance and delivers simple, accurate and reliable tuning for worldwide FM bands from 64-108 MHz and AM bands from 520-1710 kHz.
