Locations like indoor small cell operations require a high accuracy timing receiver with a determined closeness to ensure the quality of services. Until now, this proximity required an expensive and often complicated GNSS antenna installation for a few small cells. In some locations, it is not possible to deploy the Microchip IGM-1100i due to limited building materials, urban canyons, or other constraints. The Microchip IGM-1100o (also referred to as the Outdoor IGM) addresses this use case.

The IGM 1100o has a high-performance mini OCXO oscillator with aging and temp compensation. Bridge Mode available for clock class & accuracy. Provides PTP with APTS as a backup.
Powered Over Ethernet
The IGM 1100o simplifies and reduces installation costs using Microchip’s widest portfolio of PoE solutions from the inventors of PoE, making the solution plug-and-play.
Integrated Solution
The unit supports a wide temperature range. Perfect for challenging indoor scenarios to simplify the outdoor installation and reduce the space occupancy of the GPS receiver.
Extension of BestTime
The equipment supports longer sampling windows over time, mitigating the timing error in difficult indoor environments. Best in Class performance with enhanced GNSS processing (patented).
