PTP GrandMaster Clock, 32 Clients

Part Number:
IGM-1100i v2

Application:

Description

Precise synchronization of indoor small cells requires a GPS timing source, especially for phase applications. Installing a GPS antenna on the roof of the building or enabling each small cell with GPS is complicated and expensive. The revolutionary Microsemi Integrated GNSS Master (IGM) solves this problem by bringing precise GNSS-based time to indoor small cell deployments. The IGM integrates a PTP grandmaster with a GNSS receiver and antenna in a small, fully-contained package designed to be mounted to an inside wall or ceiling.
The Microsemi IGM does not use an external antenna, significantly reducing the expenses related to purchasing, installing, and maintaining the external GNSS cable systems required for typical GNSS timing receivers. Furthermore, the IGM uses Power over Ethernet (PoE) to further simplify the installation. The unit will automatically self-configure using TR-069, lock to GNSS signals, and begin PTP grandmaster operations when it is mounted on a wall or ceiling (preferably near a window). On-premise user configuration is not required.

Features:

  • Small form factor with single 1 GbE RJ45 port
  • PTP profiles: ITU-T G.8265.1, ITU-T G.8275.1 (L2 multicast), ITU-T G.8275.2 (L3 unicast), Telecom 2008, and Ethernet default
  • One-step and two-step clock
  • SyncE input, output
  • PTP input for GNSS back-up
