The IGM 1100x is perfect for scenarios where the needed GNSS antenna already exists at the desired location, or where the GNSS cabling would be short enough for low cost and easy installation, then a cost-effective solution is to deliver precise time and phase with a low-cost 1588 PTP grandmaster connected to an external GNSS antenna.

The IGM 1100x 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 1100x 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).
