摘要
Some embodiments of the present inventive concept provide a system for maintaining clock synchronization including an ultra-wideband (UWB) transmitting system and a UWB receiving system. The high precision input clock at the transmitting system produces a high precision clock frequency. A message is sent from the transmitting system including a transmit time of the message in UWB transmitter clock units. The message is received at the UWB receiving system at an arrival time in UWB receiver clock units. A time of flight (ToF) and an oscillator offset is calculated based on the transmit time included in the message and the arrival time. A tuning register uses the calculated oscillator adjustment to adjust the low precision resonator to synchronize the low precision resonator with the high precision input clock at the UWB transmitting system.
