The Time of Day (TOD) products from NetTimeLogic offer reliable synchronization for time-sensitive systems using various proprietary and industry-standard communication protocols, such as NMEA, UBX, TSIP, and ESIP. Their offerings include both a TOD Master and a Slave, implemented entirely in hardware to ensure uniform performance across systems without resorting to software or soft-core CPUs. The TOD Master generates synchronized NMEA messages to ensure consistency in distributed systems. Conversely, the TOD Slave parser interprets complex incoming signals to adjust and manage local time settings seamlessly. Providing robust solutions in critical environments, these TOD cores are vital for applications in navigation, aviation, and any scenarios where precise time-of-day information is indispensable.
