Clock Module
Clock Module
The clock module can achieve the performance of atomic clock based on DAPU's algorithm (over temperature and aging) and DAPU's high performance OCXO. Dapu can provide a variety of the synchronous and holdover clock module, to meet the different demands .
. Supports multiple reference input clocks: GPS, IEEE1588 or other clock sources)
. High holdover performance: 1.5US for 24 hours
. Quick Disciplined
It is used in LTE, LTE-Advanced, 5G base stations, digital video broadcast and general timing and Instrumentation applications.
