GENERAL DESCRIPTION
Today most FM radio stations in Europe and meanwhile
also many FM/AM radio broadcasting stations in the USA
transmit the inaudible European RDS (Radio Data
System) or the USA RBDS (Radio Broadcast Data
System) informations respectively. Likewise nowadays
receivers, most car radios and also some home and
portable radios on the market include at least some of the
RDS features.
The RDS/RBDS system offers a large range of
applications by its many functions to be implemented. For
car radios the most important are:
Program Service (PS) name
Traffic Program (TP) identification
Traffic Announcement (TA) signal
Alternative Frequency (AF) list
Program Identification (PI)
Enhanced Other Networks (EON) information.
The RDS/RBDS pre-processor is a CMOS device that
integrates all RDS/RBDS relevant functions in one chip.
The IC contains filtering and demodulation of the
RDS/RBDS signal, symbol decoding, block
synchronization, error detection, error correction and
additional detectors for multi-path, signal quality and audio
signal pauses. The pre-processed RDS/RBDS information
is available via the I
2
C-bus.
The RDS/RBDS pre-processor replaces a number of ICs
and peripheral components used nowadays in car radio
concepts with RDS or RBDS features. The integration of
the relevant RDS/RBDS data processing functions
provides, in an economic manner, high performance of
RDS/RBDS processing and reduces the real-time
requirements for the main radio microcontroller
considerably. In addition it simplifies the development of
the RDS specific software for the main controller of the
radio set.
Compared with standard radio systems, RDS/RBDS
controlled radio systems additionally require an
RDS/RBDS demodulator with a 57 kHz band-pass filter,
information about the current reception situation (reception
quality, multi-path disturbance etc.), and additional
microcontroller power for RDS/RBDS data processing,
decoding and radio control.
The new RDS/RBDS pre-processor includes all these
specific functions and meets all requirements of a high end
RDS/RBDS radio. Moreover the timing requirements of the
set controller, regarding RDS/RBDS data processing are
reduced due to the integration of decoder functions, so
that the development of radio control software can be
concentrated specifically on radio set features.
