Microchip IGM 1100i


Microchip's new ground breaking indoor wall/ceiling mounted IEEE-1588 IGM Grandmaster with integrated GNSS receiver and antenna eliminates the need for an outdoor antenna and related cabling which dramatically decreases the effective cost of the solution while providing all the performance requirements of a 1588 GM. The IGM fully integrates a 1588 PTP grandmaster with a GNSS receiver and antenna in a small, fully contained package designed for easy installation on an interior wall or ceiling. The IGM Indoor offers a quick and simple solution to bring highly accurate PTP grandmaster timing closer to mobile edge, and is ideal for LTE-A, 5G, and DOCSIS3.1 deployments.
