A redriver chip for an active copper cable is provided includes: an input signal detection module, configured for detecting a signal amplitude of an input signal; an amplitude gain control module, configured for: performing amplitude control based on a first adjustable gain so as to obtain an intermediate signal; an equalization control module, configured for: performing gain control based on a second adjustable gain, to a gain of a high-frequency part of the intermediate signal relative to a low-frequency part, so as to obtain an output signal. The chip is configured for: amplifying in equal proportions a low-frequency part of the output signal relative to a low-frequency part of the input signal and a high-frequency part of the output signal relative to a high-frequency part of the input signal.

Redriver chip, method, and device for active copper cable

An electrical device includes a core structure having a first core section, a second core section, and a third core section. The electrical device further includes a first coil electrically coupled to the first core section and the second core section to form a choke and a primary winding of a transformer. The choke is configured to reduce common mode noise for an electrical signal received by the electrical device, and the primary winding of the transformer is configured to induce a magnetic field on the third core section. The electrical device also includes a second coil electrically coupled to the third core section, which forms a secondary winding of the transformer and receives electromagnetic energy from the magnetic field induced by the primary winding of the transformer.

Electrical device with integrated transformer and common mode choke

Presented herein is a modular connector with electromagnetic interference suppression. The modular connector includes a substrate, at least one set of spring pins, and a ferrite component. Each spring in the at least one set of springs includes a first portion adjacent the substrate and a second portion extending away from the substrate. The ferrite component surrounds the at least one set of spring pins, couples the at least one set of spring pins to the substrate, and is configured to suppress electromagnetic interference.
