Microsemi TimeProvider 4100


Microsemi has introduced a new class of synchronisation product, the TimeProvider 4100 Precise Timing Gateway Clock.  TP4100 accepts multiple inputs from GNSS, SyncE, and 1588 PTP and E1/T1 digital transmission links, and distributes timing flows to multiple end points such as base stations. A gateway clock benefits from multiple layers of protection leveraging other assets in the core of the network.

A best-in-class 1588 grandmaster, TimeProvider 4100 is complemented by extensive port fan-out for PTP, NTP, SyncE, and legacy BITS. Multiple ports for current, future and legacy networks can be connected to multiple base stations for 4G and 5G deployments.   Applications include LTE-FDD, LTE-TDD, LTE-A networks, cRAN, 5G, Ethernet backhaul networks, cable, remote PHY.
