Product Overview

GPS clock synchronization module is specifically designed for SICOM3028GPT series which support PTP protocol. The GPS receiver and precise clock included in the module can provide an extremely precise GPS signal for host switches. The module also can provide high precision clock when the GPS signal is temporarily lost.
