  • Patent number: 9372503
    Abstract: A method embodiment of the present disclosure includes receiving a delay value associated with an interconnect delay that is measured across interconnect circuitry communicatively coupling a host semiconductor device with a semiconductor device. The method also includes delaying a local clock signal by an amount of delay indicated by the delay value to produce a delayed local clock signal. The method also includes receiving a delayed source clock signal, where the delayed source clock signal is received from the host semiconductor device via the interconnect circuitry. The method also includes outputting a master clock signal based on a comparison of the delayed source clock signal and the delayed local clock signal, where the master clock signal is utilized to generate one or more aligned clock signals on the semiconductor device that are aligned with a source clock signal generated on the host semiconductor device.

  • Publication number: 20160173091
    Abstract: A low voltage differential signaling generating circuit, which comprises a current source a pair of output nodes for providing a differential signal by virtue of a voltage difference therebetween, first and second differential switch circuitries and a bypass circuitry. The first differential switch circuitry selectively connects the current source to the first output node based on a control signal to cause a current flow from the first output node to the second one. The second differential switch circuitry selectively connects the current source to the second output node based on the control signal to cause a current flow from the second output node to the first one. The bypass circuitry is arranged in parallel to the first and second differential switch circuitries and is selectively switched based on an idle mode signal to prevent a current between the output nodes.
