Timing is the first requirement of human information interaction since ancient times.Nowadays,information technology and communication technology are constantly updated with each passing day,and the requirements for time-frequency synchronization of various systems are getting higher and higher. For example, today’s 5G communication network requires the time source, time transmission, and end device, time synchronization performance to reach 10 to 30ns. In order to cope with the deployment of future networks, our company has specially developed the TFT3101 series of high-precision synchronous products.
