Abstract

A method and apparatus for reducing power consumption in a communication device. In a standby mode, a relatively high power clock with a high degree of accuracy is powered down and a lower power, low frequency clock is used to maintain system synchronization. Synchronization means are provided to improve the accuracy of the low frequency clock during the standby mode.
