Abstract: A request for a high voltage mode is received and a high voltage timer is started in response to determining that a remaining amount of high voltage credits exceeds a voltage switch threshold value. A switch to the high voltage mode is made in response to the request. A low voltage mode is switched to in response to an indication. The request may be received from an application running on a data processing system. If the indication is that the high voltage timer has expired, a low voltage timer is started in response to switching to low voltage mode. If the high voltage request is still active when the low voltage timer expires, a switch back to high voltage mode occurs and a new high voltage timer is started.

Abstract: A deskewing apparatus includes a power supply connector, a oscillator, a first switch unit, a second switch unit, a first logic member, a second logic member, a clock generator and a plurality of output channels. The oscillator generates an electrical signal with a predetermined frequency and sinusoidal waveform.

The clock generator multiplies the frequency of the electrical signal based on the combination of the logic signals and converting the electrical signal from sinusoidal waveform into rectangular waveform. The output channels output the converted electrical signal.

Abstract: Systems and methods are disclosed for precise event time measurement using high-speed deserializer circuitry. The described embodiments utilize high speed deserializer circuitry to achieve a precision based upon a bit period associated with the operation of the high speed operation of the deserializer circuitry rather than upon slower speed clock periods associated with reference clock signals. In certain embodiments, the disclosed systems and methods receive an event occurrence signal and use deserializer circuitry to sample the event occurrence signal and to produce multi-bit parallel data representing the event occurrence signal. Precise timestamps can then be generated based upon the multi-bit parallel data. Advantageously, the precision of these time measurements is associated with the bit period of the high speed operation of the deserializer circuitry and are not limited to lower speeds at which other circuitry within the system may be operating, for example, based upon a slower reference clock signal.
