摘要

A system and method for controlling Radio Frequency (RF) devices. A serial RF control bus (106) provides a half-duplex serial communication interconnect path between a bus master (108) and one or more bus slaves (110). The bus master is coupled to a processor (102), and each bus slave is coupled to an RF device (104) that operates without a free-running clock. The processor controls the RF devices by sending and receiving messages over the RF control bus. The bus master and bus slaves format these messages for transmission across the RF control bus. The RF control bus includes a bi-directional data line (120), a first clock line (124), and a second clock line (122). The first clock line is asserted by the bus master when transmitting serial data to and receiving serial data from the RF slaves via the data line. The second clock line is asserted by the RF slaves when transmitting serial data to the bus master via the data line. IMAGE
