The main principle of time synchronization device is to receive standard time signals from satellites(Beidou,GPS),and processing these signals through specific or fixed algorithms and protocols
The quartz oscillator is composed of quartz resonator and oscillating circuit, which has stable frequency signal output after being powered on. Quartz oscillators according to the frequency signal output stability can be divided into general crystal oscillators, medium precision ...
CPT (Coherent population trapping) Clock is a new generation time frequency standard, which is very promising for use owing to its compactness and high performance. It is developed on the basis of atom coherent population trapping system,combining technique and method of integrated circuit manufacturing.
OCXO (Oven Controlled Crystal Oscillator) is kind of high precise frequency standard, it can generate a stable oscillation signal which is used to be time clock of various electronic devices, such as drive computer, network system, telecommunication equipment. Precision performance of time clock is directly connected with the whole system’s performance and stability. Thus, OCXO is one of essential components of electronic system.With wide establishment of 5G, the demanding for OCXO is rising quickly, one small 5G base station at least requires one OCXO, and micro site may demand for over 10 OCXO.
