Abstract: Systems and methods for processing signals are disclosed. The method may include, in a communication system comprising a plurality of devices, controlling the supply of one or more clock signals from a first clock source to one or more of the plurality of devices based on a signal communicated from a particular one of the plurality of devices to a second clock source and a request for a clock signal from one of the plurality of devices. The communicated signal may control an accuracy of the second clock source. The particular one of the plurality of devices may have highest accuracy requirements among the plurality of devices. At least one main clock signal may be generated for at least one of the plurality of devices utilizing an input clock signal received from the second clock source.

Abstract: Methods and apparatus for generating clocks for a handheld multistandard communication system are disclosed herein and may comprise receiving an input clock signal from a clock source whose accuracy is controlled by a selected device in a handheld multistandard communication system. The selected device may be characterized with a highest accuracy requirement among a plurality of devices. A main clock signal for at least one of the plurality of devices may be generated utilizing the received input clock signal. The generated main clock signal may be supplied to the plurality of devices within the handheld multistandard communication system in response to receiving a request from one of the plurality of devices. A real-time clock signal may be generated for low-power mode operation of the devices. The real-time clock signal may be generated by a real-time clock signal source and may be supplied to each device.
