The Microchip/Microsemi/Symmetricom 1510-602 is a modular Time and Frequency System built on the XLi platform for precision synchronization and timing applications. The system delivers timing accuracy better than 30 nanoseconds RMS to UTC under normal conditions and frequency accuracy better than 1×10⁻¹², with configurable dual GPS receivers and support for multiple reference inputs. Its plug-and-play architecture automatically detects system configuration, eliminating manual OS modifications and streamlining deployment in time-critical environments.
