Patent ID: 7469004

Claim:
A transmitting and receiving arrangement for a mobile radio having a baseband component and a radio-frequency component that are connected via an interface in order to interchange payload data in the transmitting and receiving directions, the interface comprising: a first differential unidirectional data link for transmission of digital payload data that is to be transmitted from the baseband component to the radio-frequency component of the mobile radio; a second differential unidirectional data link for transmission of received payload data that is converted to baseband in the radio-frequency component and of digitized, received digital payload data from the radio-frequency component to the baseband component of the mobile radio; a first word clock line operable to indicate a start of transmission of a sequence of bits on the first data link; and a second word clock line operable to indicate a start of transmission of a sequence of bits on the second data link; wherein the baseband component and the radio-frequency component are implemented in different integrated circuits.
