Abstract
An Ethernet device includes a link test pulse (LTP) generator circuit, a hybrid circuit, a transmit (TX) circuit, a receive (RX) circuit, and a post-processing circuit. The LTP generator circuit generates an LTP signal that is compliant with an IEEE 802.3 standard. The TX circuit transmits the LTP signal to an Ethernet cable through the hybrid circuit. The RX circuit receives an RX signal from the hybrid circuit during a period in which the LTP signal is transmitted through the hybrid circuit. The post-processing circuit performs a cable diagnosis of the Ethernet cable according to the RX signal.
