There exists certain scenarios where the GNSS antenna already exists at the desired location or where the GNSS cabling would be short enough to be cheap and easily installed. In such a situation, the cost-effective solution is to deliver precise time and phase with a low cost 1588 PTP Grandmaster connected to an external GPS antenna.
The Microchip Technology small form factor IEEE-1588 IGM Grandmaster with integrated GNSS receiver and external antenna delivers precise time in scenarios where a GNSS antenna is already deployed deployed or premise or where it would be cost effective to deploy, such as small 1-storey building, rack, hut or a cabinet. A single ethernet connection is used for auto-configuration management, PoE to the IGM and PTP Grandmaster operations to precisely synchronize the eNodeB's. The plug-and-play operation leveraging DHCP and TR-069 communication to the Auto Configuration Server (ACS) is meant for quick and easy installation similar to installing a typical indoor Wi-Fi antenna hot spot.
IGM-1100x provides a cost effective alternative to existing 1588 Grandmasters which typically present space, power and cost consideration hurdles.
