Abstract
A system and method is described herein for providing FDD and TDD modes of operation for a wireless communications device. The system includes a clock signal for FDD mode operation, a separate clock signal for TDD mode operation, where the TDD mode clock is twice the frequency of the FDD clock. Additionally, a counter is provided for counting bit times during a transmission or receive frame. The clock counter is reloaded after a pre-specified count is achieved. The pre-specified count is twice as great in TDD mode operation than in FDD mode operation to account for the fact that the bit periods are twice as long in FDD operation than during TDD operation since transmit and receive are at different frequencies and are not sharing the same channel.
