Product Description

CoreLogic R&D Team
Gnss Stratum 2 Timing Device Gnss Clock Synchronizer GPS-Based Time Reference Unit with Stratum 2 Performance
Product Description
GNSS Time Synchronizer with Holdover Function 
Gnss Stratum 2 Timing Device Gnss Clock Synchronizer GPS-Based Time Reference Unit with Stratum 2 Performance
CL-1021
     CL-1021 general-purpose GPS timing box with holdover function provides automatic switching 
between GPS and OCXO as the source of 1PPS, 
utilizing an adaptive tracking holdover algorithm.
     In the absence of GPS signals, it provides the 
holdover function (OCXO output) that meets the 
user's demand for a 24-hour 1PPS deviation 
of less than 1.5us. The modular design of the external solution supports any installation 
environment and orientation in the field, making it convenient for existing wireless communication 
base stations to be upgraded.
