Abstract
The present disclosure is directed to apparatuses for preventing significant amounts of common mode noise from a PHY transceiver, such as an Ethernet PHY transceiver, from coupling to an unshielded twisted-pair cable. The apparatuses can provide common mode noise isolation, while limiting any common mode noise to differential mode noise (CM-DM) conversion. Common mode noise is generally ignored by a PHY transceiver that receives a differential data signal because of differential signaling. However, when common mode noise is converted to differential mode noise, then data errors can result. Thus, limiting any CM-DM conversion is important.
