Asynchronous digital threshold detector for a digital data storage channel. |
摘要 |
<p>A zero-crossing detector for asynchronous detection of threshold transitions in a digitally sampled signal waveform. The Asynchronous Digital Threshold Detector (ADTD) receives a digitized self-clocking data readback waveform and provides the relative location of a zero-crossing within the sample period where it occurs. The digital output, which is useful for recovering data and clock signals, is in a digital form that can be used directly by a certain class of asynchronous digital phase detector systems. The ADTD is entirely digital and can be embodied in a low power configuration using CMOS technology. <IMAGE></p> |
