DP83822I: Heartbeat and loopback function

Part Number: DP83822I


Hi team,

Could you give me comments on more detail but basic information about heartbeat and loopback function as described in the datasheet below? Or is there any application note about this topic?

「8.4.5 10BASE-Te

The 10BASE-Te transceiver module is IEEE 802.3 compliant. It includes the receiver, transmitter, collision, heartbeat, loopback, jabber, and link integrity functions, as defined in the standard.」

Best regards,

Takeshi Sasaki
