  • Apparatus and method for selectively enabling and disabling a squelch circuit across AHCI and SATA power states
    Patent number: 8686757
    Abstract: An apparatus and a method are provided for selectively enabling and disabling a squelch circuit in a Serial Advanced Technology Attachment (SATA) host or SATA device while maintaining proper operation of the host and device. An apparatus and method are provided which allow the squelch circuit to be selectively enabled and disabled across SATA power states (PHY Ready, Partial, and Slumber) and in Advanced Host Controller Interface (AHCI) Listen mode.
    Type: Grant
    Filed: March 19, 2012
    Date of Patent: April 1, 2014
    Assignee: Intel Corporation
    Inventors: Jien-Hau Ng, Tea M. Lee

  • Serial advanced technology attachment device presence detection and hot-plug in low power mode
    Patent number: 7565457
    Abstract: A method, circuit, and system are disclosed. In one embodiment, the method comprises sending a step pulse across a serial advanced technology attachment (SATA) transmission line, determining the length of time the transmission line takes to charge from common mode voltage to supply voltage, and determining whether a device is connected to the SATA transmission line based on the length of the transmission line charge time.
