    摘要： A device to access and/or verify connections between a chip package and a printed circuit board (“PCB”), specifically within packages lacking back-side measurement access, includes a housing for insertion between the chip package and PCB. A passageway in the housing connects an entrance and an exit from the housing. The entrance is disposed on an end of the housing facing away from the chip package. The exit is disposed on a side of the housing below the chip package such that the passageway is directed at a signal path between the chip package and the PCB. A conductor disposed in the passageway is movable between a retracted position in which a contact end of the conductor is disposed within the passageway of the housing and an extended position in which the contact end of the conductor is disposed outside of the housing and in contact with the signal path.

    摘要： A device for connecting a plurality of assemblage-mounted optical transmitters to a plurality of assemblage-mounted optical receivers mounted on a selected side of an assemblage includes a planar frame configured to be coupled to the selected side of the assemblage. A plurality of first redirecting structures is affixed to the planar frame and each is configured to receive a first optical signal from a different assemblage-mounted optical transmitter. Each first redirecting structure transmits a second optical signal, corresponding to the first optical signal, along a preselected path. A plurality of second redirecting structures is affixed to the planar frame and each is configured to receive the second optical signal from a different one of the first redirecting structures. Each of the second redirecting structures transmits a third optical signal, corresponding to the second optical signal, to a different one of the assemblage-mounted optical receivers.

    摘要： A phase locked loop generates an output corresponding to a source synchronous input and an input link clock signal. A phase locking feedback system receives the input and an input link clock signal and detects phase deviations between the output and the input. The phase locking feedback system also adjusts an adjusted clock signal based on the phase deviations thereby causing the phase locking feedback system to generate the output so that the output has a steady phase relationship with the input. A first mechanism causes the phase locking feedback system not to track phase deviations between the output and the input upon occurrence of a first predefined event, thereby maintaining the adjusted clock signal at a current state.
