Si4684-A10
Single-Chip, FM/DAB/DAB+ Radio Receiver
Description
The Si4684 single-chip digital receiver is one member of a
family of 100% CMOS digital radio broadcast receiver ICs
from Silicon Labs. The Si468x family offers a complete and
cost-effective digital radio solution integrating the RF tuner,
baseband and audio processing on a single die. The high
level of integration provides significant customer benefits
compared to traditional digital radio solutions, including a
reduction in system implementation complexity, validation
and testing, and improved reliability and manufacturability.
The Si4684 offers VHF Band III (168-240 MHz) reception
capability and is fully compliant with ETSI EN 300 401 and
ETSI TS 102 563. The Si4688 supports DAB and DAB+ via
an integrated source decoder that supports both MPEG
Audio Layer 2 (DAB) and HE-AAC V2 (DAB+). The Si4684
supports data services such as Dynamic Labels, Intellitext,
Electronic Program Guide (EPG), Slideshow and
Journaline® with the appropriate external decoders.
The Si4684 additionally supports worldwide 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.
