ABSTRACT:
A clock and phase detect algorithm detects the best sample result for back-end system to recover the sample clock from front-end system. The algorithm of the present invention gets the sample result from ADC by applying slope variation sum (SPVS), which is used in turning points of sample result. The exact sample clock will always get the maximum SPVS value no matter how special or difficult the pattern is. It can detect not only most of normal patterns, but also the special patterns like block, linear piece pattern. The use of SPVS result allows back-end systems to distinguish which clock is the exact clock to sample the analog signal, and make the back-end convert quality is almost the same as the front-end. This function can be operated by system maker and maintain the quality of display automatically, no manual operation is need.
