Abstract
Circuitry of a physical layer for interfacing with a communication bus of a wired local area network is disclosed. The circuitry includes a variable delay driver operably coupled to a communication bus. The communication bus includes a shared transmission medium. The variable delay driver is configured to control a slew rate of a driven transmit signal at the driver output. The circuitry also includes receiver circuitry operably coupled to the communication bus. The circuitry further includes a common mode dimmer operably coupled to the receiver circuitry and the communication bus. The common mode dimmer is configured to protect the receiver circuitry from common mode interference.
