摘要： Embodiments of the present invention may provide a system with a first and second circuit system separated by an electrical isolation barrier but provided in communication by at least one isolator device that bridges the isolation barrier. The first circuit system may include a communication system to transmit data across a common isolator device as a series of pulses, and the second circuit system may receive the series of pulses corresponding to the data. The second circuit system may include a detector coupled to the common isolator device to detect the received pulses, a oneshot to frame the received pulse(s), and a controller to reconstruct the data based on accumulated framed pulse(s). Therefore, noise induced spurious pulses outside the oneshot intervals may be ignored by the second circuit system providing improved noise immunity.

摘要： A clock system includes a digital phase/frequency detector (DPFD), a buffer, a digitallycontrolled oscillator (DCa) including a sigma- delta modulator (SDM), an adder, a first frequency divider. The DPFD may have a first input for a reference input clock, a second input for a feedback signal, the DPFD generating an output representing a difference between the reference input clock and the feedback signal. The buffer may be coupled to the DPFD for accumulating the difference signal over time. The sigma-delta modulator (SDM) may have a control input coupled to the buffer. The adder may have inputs coupled to the (SDM) and a source of an integer control word.
