Abstract :
The receiver system is an important part of FAST (Five-hundred-meter Aperture Spherical Radio Telescope) and plays a key role in determining the performance of the telescope. The receiver design requires synchronization among the digital instruments and accurate timestamp, because time synchronization of astronomical data before and after it is recorded and processed is of vital importance for the time accuracy and stability of the receiver.
