The Springwave’s IS3300 series is a IEEE1588v2 PTP (Precision Time Protocol) boundary clock to build the precision time and frequency synchronization based on the IEEE1588v2-2008 standard. Especially, it is designed for the economic deployment and precision synchronization in the SCADA system and the 4G/LTE mobile network. Also it supports up to three different IP domain to accommodate different groups of the PTP clients. There are three UTP connectors in the front to interface PTP clients. Also it supports pass-through mode to by-pass the user traffic from mixed user and PTP packets.



Precision Time Synchronization


Currently the base stations in the 4G/LTE small cell networks are increasing caused by the tremendous mobile data traffic growth, like smartphone. Furthermore, these base stations are demanded on the precision time/frequency synchronization, and the equipment is increasing coming from their narrow RF coverage. 

The IS3300 boundary clock is integrated advanced Springwave’s own algorithm(SPW1588™) to synchronize precise time to the PTP master.
