of host 510 changes to 1 6 ghz due to a change in ambient operating temperature or the like in a conventional sata interface system host 510 would transmit data d 1 to attached device 520 at the changed transmission frequency f 1 of 1 6 ghz using first transmitter 515 then attached device 520 would receive the data signal d 1 u2032 detect a transmission frequency of f 1 1 6 ghz from the received data signal d 1 u2032 and determine whether the detected transmission frequency f 1 is within its receiver offset range of 1 45 ghz to 1 65 ghz since the detected transmission frequency f 1 1 6 ghz would be within the receiver offset range of 1 45 ghz to 1 65 ghz for attached device 520 it would transmit a data signal d 2 u2032 to host 510 at the standard transmission frequency of f 2 1 5 ghz however since the receiver offset range for host 510 has been changed to 1 55 ghz to 1 65 ghz due e g to the change in ambient operating temperature the standard transmission frequency of 1 5 ghz would be detected from data signal d 2 u2032 received from attached device 520 and would be determined to fall outside of the receiver offset range of 1 55 ghz to 1 65 ghz for host 510 as a result.
