Abstract:
1. A radio frequency (RF) to baseband interface coupling an RF section for processing RF signals to a baseband section for processing baseband signals, the interface comprising: a bi-directional message serial interface for communicating multi-purpose messages between the RF section and the baseband section; and a data serial interface for communicating signal sample data from the RF section to the baseband section, the data serial interface comprising a data clock signal line and a single data bit signal line to carry a data clock signal and to serially carry the signal sample data, respectively, the signal sample data including sign bits and magnitude bits, wherein the data clock signal line carries the data clock signal comprising rising edges and falling edges, and the sign bits are valid on the falling edges of the data clock signal and the magnitude bits are valid on the rising edges of the data clock signal, each rising and falling edge including a pairing of the sign and magnitude bits.
