Description

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 mm

high integration and complete system production test

simplifies

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.
