A network device comprises an interface coupling an electronic device to a differential pair of signal lines, and an integrated active common mode suppression and electrostatic discharge protection circuit coupled to the interface in parallel to differential signal lines of the electronic device. First and second resistors are respectively coupled to the differential lines between the integrated active common mode suppression and electrostatic discharge protection circuit and the electronic device.

Electrostatic discharge protection circuit

An integrated circuit includes current mode drivers that provide equalized outputs. A parallel-to-serial converter circuit receives data at less than one fourth the output data rate, and provides main data and equalization data at one fourth the output data rate to at least one four-to-one multiplexer. The main data and equalization data is multiplexed onto an output node at the output data rate.

A network device comprises an interface coupling an electronic device to a differential pair of signal lines, and an integrated active common mode suppression and electrostatic discharge protection circuit coupled to the interface in parallel to differential signal lines of the electronic device.

Embodiments disclosed herein describe a network device including a class AB common mode suppression (CMS) circuit coupled in parallel between a line voltage source and a physical layer (PHY) device that provides active EMI suppression and Phy device termination. A network connector is coupled to provide the line voltage source to the class AB CMS circuit. The class AB CMS circuit provides current to the PHY device, terminates open-drain transmit drivers of the PHY device and suppresses common mode noise thereby minimizing electromagnetic interference. In other embodiments, the class AB CMS circuit is coupled in parallel between the network connector and a physical layer (PHY) device. The class AB CMS circuit suppresses common mode noise, and terminates open-drain transmit drivers of the PHY device, thereby minimizing electromagnetic interference.

Embodiments disclosed herein describe an isolated switched-mode power supply with its output regulated from the primary side, by generating a sensing current using a sensing element coupled to the output of the power supply, and measuring a scaled version of the sensing current which depends on the output voltage, and calculating an estimate voltage representing the output voltage, and regulating the output of the isolated switched-mode power supply based on the estimate voltage.
