Description
The Si4702/03-C19 extends Silicon Laboratories Si4700/
01 FM tuner family and further increases the ease and
attractiveness of adding FM radio reception to mobile
devices through small size and board area, minimum
component count, flexible programmability, and superior,
proven performance. The Si4702/03 leverage Silicon
Laboratories' highly successful and patented Si4700/01 FM
tuner, and are pin and software compatible to existing
Si4700/01 FM tuner designs. The Si4702/03 benefits from
proven digital integration and 100% CMOS process
technology, resulting in a completely integrated solution.
The Si4702/03 proven and highly flexible functionality
caters to the subjective nature of audio preferences and
variable FM broadcast environments worldwide.
The Si4703-C19 incorporates a digital processor for the
European Radio Data System (RDS) and the US Radio
Broadcast Data System (RBDS) including all required
symbol decoding, block synchronization, error detection,
and error correction functions. RDS enables data such as
station identification and song name to be displayed to the
user.
standard view, allowing adopters to selectively choose
granularity of RDS status, data, and block errors. Si4703
software is backwards compatible to the proven Si4701,
adopted
manufacturers worldwide.
The Si4702/03 device’s high level of integration and
complete FM system increases quality to manufacturers,
improves
manufacturing and final testing.
