    摘要: An apparatus comprises a differential equalizer having: a) a first differential input, b) a second differential input, c) a first differential output, and d) a second differential output; a frequency detector coupled to the first and second differential inputs; an amplifier coupled to a first differential output and a second differential output of the differential equalizer; and a logical combiner having a first input coupled to an output of the frequency detector and an output coupled to a control input of the amplifier, wherein the logical combiner can mask at least one received de-emphasis parameter.

    摘要: With conventional redrivers used for external Serial Advanced Technology Attachment (eSATA), there is no ability to indicated to a host that an external device (like a hard disk drive) is not present. As a result, power is consumed by a host because of nearly continual transmission of communication reset signals. Here, a redriver has been provided that includes a cable disconnect terminal and circuitry within a controller that is able to detect whether an external device is present. This redriver enables a host to be powered down or placed in a low power mode while also enabling the use an eSATA compliant connector.
