Publication number: 20190025872Abstract: Methods and USB devices correlating clock domains are presented. A USB device includes at least one signal line adapted to carry signals in a first clock domain. The signals are received from a USB host. A clock operates a second clock domain. A periodic packet detection circuit detects a missing periodic packet from the signals received in the first clock domain. A device controller correlates a USB operation in the second clock domain with the first clock domain based on the periodic packet detection circuit detecting the missing periodic packet. A USB device includes at least one signal line carrying UTMI or ULPI signaling. A USB controller decodes packet identification from the UTMI or ULPI signaling. A periodic packet detection circuit, separate from the USB controller, decodes packet identification from the UTMI or ULPI signaling.Type: ApplicationFiled: July 18, 2017Publication date: January 24, 2019Inventors: Ren Li, Peter Shah, Matthew Sienko, Hui-ya Liao Nelson, Stefan Rohrer, Arash Mehrabi, Stefan Mueller, Ralf Herz, Magesh Hariharan, Maoxin Wei

Patent number: 8060674Abstract: An integrated data storage control system provides, in a single integrated circuit, RDC, servo logic, ATA interface, microprocessor, and other formerly discrete components in one highly integrated system design. The integrated circuit is rendered using a single integrated circuit technology type (e.g., digital CMOS) for all components. Analog and digital circuits are combined in such a way as to eliminate or reduce noise or interference in digital circuits from analog circuit components. Individual elements may have their outputs and inputs MUXed together such that individual elements can be selectively switched (during testing modes) such that the integrated circuit emulates or behaves in the same or similar manner as one of the prior art components. The present invention may be applied to magnetic hard disk drives (HDDs) or other types of storage devices such as floppy disk controllers, optical disk drives (e.g., CD-ROMs and the like), tape drives, and other data storage devices.Type: GrantFiled: May 5, 2009Date of Patent: November 15, 2011Assignee: Broadcom CorporationInventors: Siamack Nemazie, Kaushik Popat, Balaji Virajpet, William R.

Patent number: 6314480Abstract: An integrated HDD system provides, in a single integrated circuit, RDC, servo logic, ATA interface, microprocessor, and other formerly discrete components in one highly integrated system design. The integrated circuit is rendered using a single integrated circuit technology type (e.g. digital CMOS) for all components. Analog and digital circuits are combined in such a way as to eliminate or reduce noise or interference in digital circuits from analog circuit components. The invention takes advantage of existing circuit design modules provided in the integrated circuit as “hard block” components which are unchanged by integrated circuit design software. Changes in operability of the overall integrated circuit may be readily achieved by altering “soft block” components to customize or tailor the design for a particular hard drive.Type: GrantFiled: November 8, 1999Date of Patent: November 6, 2001Assignee: Cirrus Logic, Inc.Inventors: Siamack Nemazie, Kaushik Popat, Balaji Virajpet, William R.
