Over the useful life of a product, technology usually advances to the point where higher performance devices could be designed and attached via a serial link which would enhance the product's capability and/or performance. A serial link designed to operate with devices at various, selectable, high speed data rates can take advantage of these technology advances as they occur, even though the specific frequencies that will be required in the future are not known at the time of the initial link design. This can be accomplished using a frequency discrimination technique as described below.
