Abstract:

Clock spreading systems and methods are disclosed. In one embodiment of the invention, a clock spreading system is provided in an integrated transceiver system that comprises a base band control system and a transceiver coupled to the base band control system. The clock spreading system provides a spread clock output signal derived from a clock reference signal for clocking one of the base band control system and the transceiver. The clock spreading system is configured to provide a periodic phase modulated spread clock output signal during receiving of data in a receive mode and a pseudo-random phase modulated spread clock output signal during transmitting of data in a transmit mode.
