  • Patent number: 8559530
    Abstract: In some embodiments, the inventions includes a transmitter including a cycle encoding circuit to receive a data input signal and to provide a full cycle encoded signal in response thereto by continuously joining portions of different encoding signals. Some of the encoding signals have a different frequency than others of the encoding signals and some of the encoding signals have a different phase than others of the encoding signals. Data is represented in data time segments of the full cycle encoded signal and no data time segment has more than one cycle of an encoding signal. In some embodiments, a receiver receives the cycle encoded signal and recovers data of the data input signal.

  • Patent number: 7019550
    Abstract: A method includes providing a device under test (DUT) which has an input port and an output port. The DUT also has a squelch detector which is coupled to receive a signal from the input port. The DUT also has a receiver amplifier coupled to receive a signal from the input port. In addition, the DUT also has a transmitter to transmit data signals from the output port. The method further includes providing a loopback connection from the output port to the differential input port. The method also includes controlling the transmitter to transmit a test signal from the output port to the input port. The method includes monitoring at least one of respective outputs of the receiver amplifier and the squelch detector to determine whether a leakage condition exists in the DUT. Other embodiments are described and claimed.

  • Patent number: 7009431
    Abstract: According to some embodiments, an interpolated clock signal having a first frequency is received, and the interpolated clock signal is periodically sampled based on a reference clock signal to generate periodically-sampled values, the reference clock signal having substantially the first frequency. A phase of the interpolated clock signal may be set to a phase degree at which the periodically-sampled values resolve to more than one value, and the phase of the interpolated clock signal may be incrementally changed until the periodically-sampled values resolve to one value. A non-linearity of the interpolated clock signal may be determined based on the number of incremental changes.

  • Patent number: 6466074
    Abstract: A clock splitter device for forming a clock/inverted clock signal pair. The input clock signal is sent through an initial buffer stage and applied to two parts of a second stage. The second stage includes a single stage buffer and constricted inverter to provide two inverted outputs. The transistor arrangement of these two parts provides an equal delay to the two signal paths. The outputs of these two parts are sent to identical output buffers. Because the two paths have identical transistor delays, and since the metal paths on the board are arranged to have identical delays, the two paths can very low skew therebetween.
