SERIAL RADIO FREQUENCY TO BASEBAND INTERFACE WITH PROGRAMMABLE CLOCK

摘要

An interface (206) between an RF processing section (202) and a baseband processing section (204) supports general purpose message transmission as well as satellite positioning system signal sample transmission between the RF processing section (202) and the baseband processing section (204). The interface includes a bi- directional message serial interface (208) and a data serial interface (210). The complexity of the data serial interface may be minimized by using a single data bit signal line in the data serial interface.
