Si4732-A10
Broadcast AM/FM/SW/LW/RDS Radio Receiver
Description
Features
The Si4732-A10 digital CMOS AM/FM/SW/LW/RDS radio
receiver IC integrates the complete broadcast tuner and
receiver function from antenna input to digital audio output.
The device leverages the Silicon Labs broadcast proven
digital low-IF architecture, enabling a cost-effective digital
audio platform for consumer electronic applications with
high TDMA noise immunity, superior radio performance,
and high fidelity audio power amplification. Offering
unmatched integration and PCB space savings, the
Si4732-A10 requires only a few external components and
less than 15 mm2 of board area, excluding the antenna
inputs. The Si4732-A10 AM/FM/SW/LW/RDS radio
provides the space savings and low power consumption
necessary for portable devices while delivering the high
performance and design simplicity desired for all AM/FM/
SW/LW/RDS solutions.
- Worldwide FM band support (64–108 MHz)
- Worldwide AM band support (520–1710 kHz)
- SW band support (2.3–26.1 MHz)
- LW band support (153–279 kHz)
- Excellent real-world performance with integrated AM/
FM/SW/LW/RDS
- Integrated VCO
- Advanced AM/FM seek tuning
- Automatic frequency control (AFC)
- Automatic gain control (AGC)
- Digital FM stereo decoder
- Programmable de-emphasis
- Advanced Audio Processing
- Seven selectable AM channel filters
- AM/FM/SW/LW digital tuning
- EN55020 compliant
- No manual alignment necessary
- Programmable reference clock
- Adjustable soft mute control
- RDS/RBDS processor
Leveraging Silicon Laboratories' proven and patented
Si4700/01 FM tuner's digital low intermediate frequency
(low-IF) receiver architecture, the Si4732-A10 delivers
superior RF performance and interference rejection in the
AM, FM, SW, and LW bands. The high level of integration
and complete system production test simplifies design-in,
increases system quality, and improves reliability and
manufacturability.
