3.1 DP83822

The DP83822 is an ultra-robust, low-power single-port 10/100 Mbps Ethernet PHY. Both 100Base-TX and 100Base-FX are supported. DP83822 has gone through Cable Break Tests to validate how link loss is indicated in a timely manner. More information can be found in DP83822 Cable Break Test for Profinet Compliance.
