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.
