Abstract
Equalization for ports of a crosspoint switch at least partially offsets transmission losses such as skin loss. The equalization may be tailored on a port-by-port basis using adaptive equalization or adjustable equalization, but fixed equalization may be used. In some implementations, each input port or output port of a crosspoint switch has a dedicated equalization circuit that has filtering characteristics that are based on the signal characteristics (e.g., jitter) measured at the affected output port. For an adjustable equalization approach, the adjustable equalization circuitry includes various switched connections that are selectively coupled and decoupled to achieve the target level of equalization.
