Si4624-A10
High-Performance, Single-Chip FM/DAB/DAB+/RDS/RBDS
Data Receiver
Description
The Si4624 single-chip digital receiver is a 100% CMOS
digital radio broadcast receiver IC from Silicon Labs. It
provides significant advances in size, power consumption,
and performance to enable DAB/DAB+ data services
reception in automotive infotainment systems and car
radios.
The Si4624 offers a complete and cost-effective platform to
support global analog VHF Band II and digital VHF Band III
radio standards by integrating multiband RF tuner,
demodulator, and channel decoder on a single die. The
high level of integration and complete system production
test simplifies design-in, increases system quality, and
improves reliability and manufacturability.
The Si4624 incorporates a fully integrated decoder for the
European Radio Data System (RDS) and the North
American Radio Broadcast Data System (RDBS), including
all required symbol decoding, block synchronization, error
detection, and error correction functions.
The Si4624 additionally supports digital DAB and DAB+
data reception, incorporating digital channel demodulation
and decoding functions.
Leveraging Silicon Laboratories' proven and patented
digital low intermediate frequency (Low-IF) receiver
architecture, the Si4624 delivers superior RF performance
and interference rejection. The solution offers auto-
calibrated digital tuning, and proven FM seek functionality
based on multiple signal quality and band parameters. In
addition, the Si4624 provides an integrated clock oscillator
or accepts a reference clock and supports a selectable
control interface (SPI or I
2
C).
The Si4624 receiver system requires a minimal bill of
materials and offers low power consumption, making the
solution ideal for today’s infotainment systems.
