Comparison of Device Features

The DP83TG721-Q1 enables very high time synchronization accuracy for automotive applications. Compared to the DP83TG720x series, the DP83TG721-Q1 offers advanced diagnostic tools, hardware time stamping, TC-10 low power sleep, and has integrated Audio Video Bridging (AVB). Comparison Between DP83TG720x and DP83TG721x provides an overview of feature differences between the two.
