Abstract
A data regeneration device regenerates a digital signal in a low-speed pass-through mode of operation, performs an upstream link equalization procedure on an upstream data link in an equalization mode of operation, performs a downstream link equalization procedure on a downstream data link in the equalization mode of operation, and regenerates the digital signal in a high-speed pass-through mode of operation. The data regeneration device transitions seamlessly from the low-speed pass-through mode of operation to the equalization mode of operation in compliance with a communication protocol. Moreover, the data regeneration device synchronizes completion of the upstream link equalization procedure with completion of the downstream link equalization procedure so that the data regeneration device transitions seamlessly from the equalization mode of operation to the high-speed pass-through mode of operation in compliance with the communication protocol.
