An apparatus for equalizing channels is provided, which is generally transparent to link training. The apparatus generally includes equalization paths formed by an input circuit, a crossbar, and an output circuit and a controller. Each equalization path is coupled to at least one of the channels, and a controller has a VGA loop, a crossbar loop, and a driver loop. The AGC loop receives a first reference voltage and provides a gain control signal to the input circuit, and the gain control network comprises a replica of at least one of the equalization paths. The crossbar loop receives a second reference voltage and provides a crossbar control signal to the crossbar. The driver loop receives a third reference voltage and provides a driver control signal for the output circuit.
