PTP GrandMaster Clock, 32 Clients

Part Number:
IGM-1100o v2

Application:

Description

The synchronization needed for indoor small cell operations requires a high accuracy timing receiver nearby. Until now, this proximity required an expensive and often complicated GNSS antenna installation for a few small cells. In some scenarios, it is not possible to deploy the Microsemi IGM-1100i due to limited building materials, urban canyons, or other constraints. The Microsemi IGM‑1100o (also referred to as the Outdoor IGM) addresses this use case. The IGM‑1100o brings precise timing indoors and serves indoor small cells, but is located on the roof of the building instead of on a wall or ceiling.

The Microsemi IGM-1100o does not require Assisted-GNSS as it is placed outdoors, where GNSS signal reception is optimal. However, in urban canyons or other situations where GPS reception is challenging, the Outdoor IGM can leverage Assisted-GNSS. The IGM‑1100o uses Power over Ethernet (PoE) to further simplify the installation. When mounted on the roof and connected to the network with PoE, the unit automatically self-configures through TR-069, locks to GNSS signals, and begins PTP grandmaster operations. On-premise user configuration is not necessary.
