The DP83TG721-Q1 integrates IEEE 1588v2/802.1AS timestamping and other additional hardware engine to offer sub 15 nanosecond synchronization accuracy.

The DP83TG721-Q1 is also capable of providing a wide range of high quality time synchronized clock (1KHz to 50MHz) and generate synchronous patterns on GPIO's. This enables the DP83TG721-Q1 to achieve system level synchronization for ADAS sensor data synchronization, Corner Radar Chirp synchronization, 1 pps signal for GPS, LIDAR, V2x, etc.
