A pulse receiving circuit constituting a signal transmission device includes a first pulse detector that receives a differential input between a first reception pulse signal, i.e. an internal signal at a secondary winding of a first transformer and a second reception pulse signal, i.e. an internal signal at a secondary winding of a second transformer; a second pulse detector that receives the differential input between the first reception pulse signal and the second reception pulse signal with input polarity reversed to that of the first pulse detector; and a logic unit that generates a reception pulse signal based on output signals of the first and second pulse detectors, respectively.

A Power Over Data Lines (PoDL) system includes Power Sourcing Equipment (PSE) supplying DC power and differential Ethernet data over a single twisted wire pair to a Powered Device (PD). Due to start-up perturbations, PD load current variations, and other causes, dV/dt noise is introduced in the power signal. Such noise may be misinterpreted as data unless mitigated somehow. Rather than increasing the values of the passive filtering components conventionally used for decoupling/coupling the power and data from/to the wire pair, active circuitry is provided in the PSE, PD, or both to limit dV/dt in the power signal. Such circuitry may be implemented on the same chip as the PSE controller or PD controller. Therefore, the sizes of the passive components in the decoupling/coupling networks may be reduced.
