  • Method and apparatus for a real time signal integrity oscilloscope
    Patent number: 8219339
    Abstract: A system, method, and apparatus for obtaining a record of logic level transitions within a signal, and for accurately determining a voltage-time pair exhibited by the signal. To achieve these ends, a front-end device may be mated to a real-time sampling system, such as an oscilloscope. The front-end device effectively permits the oscilloscope to observe signals exhibiting greater data rates than otherwise possible without the front-end device.
    Type: Grant

  • Method and apparatus for clock recovery
    Publication number: 20060193418
    Abstract: A clock recovery system includes a rough clock generator, which yields a rough clock signal, based upon logic level transitions exhibited by a data signal. The rough clock signal is supplied to a phase locked loop having an adjustable order of frequency response, an adjustable corner frequency, an adjustable natural frequency, and/or an adjustable damping factor. The clock recovery system includes control parameters that, when properly adjusted, suppress non-ideal effects of components within the clock recovery system, and also permit the frequency response of the phase locked loop to be returned to a desired response.
