The present invention relates to synchronization circuitry that is used to synchronize an asynchronous received RF message with a transmitted RF message. In one embodiment of the present invention, the synchronization circuitry includes at least one counter, which is used to associate timing of the asynchronous received RF message with a receive count value, and associate timing of the transmitted RF message with a transmit count value. A time delay between occurrence of the receive count value and the transmit count value provides accurate timing for the start of the transmitted RF message.
