摘要: A receiving device within a digital electronic system includes a sampling unit, a voter block, and a local clock phase adjustment unit. The sampling unit samples an input line at three points in time at intervals of one half of a bit period. The sampling unit delivers the values obtained in the sampling process to the voter block. The voter block determines whether to deliver an up or a down vote to the local clock phase adjustment unit. The voter block communicates with the local clock phase adjustment unit via up and down control signals. The local clock phase adjustment unit determines whether the local clock phase should be adjusted, and if so, whether to advance or delay the local clock phase. If certain meta-stable conditions are observed by the voter block, the voter block will vote in one direction in order to push the system out of the meta-stable condition.

摘要: CMOS optical receiver and optical transmitters are described. The optical receiver is formed from a CMOS CCD which is modified to immediately output all information indicative of incoming light, i.e., with no transfer gate. The optical transmitter is formed of a modulation window device. Both the optical transmitter and optical receiver are located on-chip with a microprocessor and form the I/O for the microprocessor. Since the modified I/O is serial, a serial to parallel converter, and parallel to serial converter are provided.
