Si4830
Broadcast Mechanical Tuning AM/FM Radio Receiver
Description
Features
The Si4830 is the first wheel-tuned digital CMOS AM/FM
radio receiver IC that integrates the complete receiver
function from antenna input to audio output. Leveraging
Silicon Laboratories' proven and patented digital low
intermediate frequency (low-IF) receiver architecture, the
Si4830 delivers superior RF performance and interference
rejection in both AM and FM bands. Additionally, the digital
core provides advanced audio conditioning for all
environments, removing pops, clicks, and loud static in
variable signal conditions. The superior control algorithm
integrated in Si4830 provides easy and reliable control
interface while eliminating all the manual tuned external
components used in traditional solutions.
Like other successful audio products from Silicon Labs,
Si4830 offers unmatched integration and PCB space
savings with minimum external components and less than
20 mm2 of board area, excluding the antenna inputs. The
high integration and complete system production test
simplifies design-in, increases system quality, and
improves manufacturability. The receiver has very low
power consumption, runs off two AAA batteries, and
delivers the performance benefits of digital tuning to the
legacy analog radio market.
- Worldwide FM band support (64–108 MHz)
- Worldwide AM band support (520–1710 kHz)
- Selectable support for all AM/FM regional bands
