Abstract: Techniques for detecting a digital pseudo-random sequence (PRS) using fast locking, including repeatedly computing a first PRS seed based on an ADC output, generating a PRS sequence based on the first seed, computing a second PRS seed based on the sequence, and comparing the sequence to the ADC output (comparison results may be provided as a bool signal), until the sequence matches the ADC output. Thereafter, the technique may include re-computing the sequence based on the second seed, re-computing the second seed based on the re-computed sequence and comparing the re-computed sequence to the ADC output. The technique may further include setting a lock when a threshold number of sequences computed from the second seed match the ADC output, and reverting to computing the sequence based on the first seed if a sequence computed from the second seed does not match the ADC output and the lock is not set.
