Abstract:
The present invention relates to a high speed interface for radio systems, in particular to a synchronous serial digital interface for car radio. In an its embodiment the synchronous serial digital interface for at least dual radio receiver systems comprises a master device and a slave device; said dual radio receiver systems having an intermediate frequency; said master device and said slave device exchange data in bi-directional way on at least one communication channel; said master device and said slave device have a unique bit clock; said master device supply to said slave device a synchronisation signal; said synchronisation signal have frequency spectrum with an amplitude at said intermediate frequency lower than at the other frequencies.
