Abstract: A serial ATA interface (300) calibrates serially connected components of a computer system (320) linked by the interface to a negociated data transmission speed. The interface negociates the fastest data transmission speed supported by the serially connected components. Link parameters associated with the negociated data transmission speed are cablirated and implemented in a Physical layer of the interface data before data is transmitted accross the interface. The cablirated link parameters include signal settings for amplitude, pre-emphasis, equalization and timing. Default settings of the link parameters correspond to the slowest data transmissio speed supported by the serially connected components. The serially connected components are calibrated each time system power is initialized, the serially connected components can be a host computer (310) linked to a data storage device such as a backplane-base storage subsystem (320).
