  • Phase locked loop reconfiguration
    Patent number: 6621353
    Abstract: Dedicated registers sequenced by a state machine capture phase locked loop reconfiguration values or parameters and load them into a reconfigurable phase locked loop in order to achieve rapid and reliable reconfiguration with high immunity from clock glitches and jitter as the phase locked loop goes in and out of lock. In the preferred environment of a digital bus, reconfiguration values or parameters can be supplied through a normal bus transaction and no dedicated connections are required for phase locked loop reconfiguration.
    Type: Grant
    Filed: November 7, 2001
    Date of Patent: September 16, 2003
    Assignee: International Business Machines Corporation
    Inventors: Timothy Carl Bronson, David Andrew Thorndike
