ALL DIGITAL HIGH SPEED ALGORITHMIC DATA RECOVERY METHOD AND APPARATUS USING LOCALLY GENERATED COMPENSATED BROAD BAND TIME RULERS AND DATA EDGE POSITION AVERAGING )

摘要

All digital data algorithm recovery methods and devices operate with jitter greater than 25%, run length is greater than 1000 bits, and use self-calibrated delay elements to phase-align locally generated time to data average transmission locations. The sampling time for recovering data from the binary collection sequence at the center of the data eye is reliably set. The phased mojigan signal is used to sample the transmission location of the data and the sampled data is analyzed statistically in the state machine. Here, the time he first and second a broadband signal consisting of mood frequency, a period from the frequency F _R is the receiver local clock frequency and the same F _T is 1 / F _R a receiver local clock frequency equal to the frequency of the drive clock and _T is equal to F is the 1 / F _R -F _T, such as the frequency of the drive clock.
