A method and system for synchronous transfer of bitstream data between a power-driver chip and a digital signal processing chip in a digital radio frequency transmit system is disclosed. A master phase-locked-loop located in the power-driver chip is utilized to provide master clocking control for the digital radio frequency transmit system. Furthermore, the clocking method and system is configurable to secure precise carrier frequency positioning of a digitally-generated radio frequency signal based on predetermined chip frequencies unrelated to the carrier frequency, assuring low bitstream phase noise at the output of the power driver chip. |
