Si4629-A10
High-Performance, Single-Chip AM/FM/HD/DAB/DAB+/RDS/RDBS
Data Receiver
Description
The Si4629 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 HD Radio/DAB/DAB+ services
reception in automotive infotainment systems and car
radios.
The Si4629 data receiver offers a complete and cost-
effective platform to support global analog and digital AM,
FM, and 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 Si4629 supports worldwide analog AM and FM radio
reception and 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.
Leveraging Silicon Laboratories' proven and patented
digital low intermediate frequency (Low-IF) receiver
architecture, the Si4629 delivers superior RF performance
and interference rejection. The solution offers auto-
calibrated digital tuning, and proven AM/FM seek
functionality based on multiple signal quality and band
parameters. The Si4629 offers highly flexible and
advanced audio FM stereo-mono blend. In addition, the
Si4629 provides an integrated clock oscillator or accepts a
reference clock and supports a selectable control interface
(SPI or I
2
C).
