Abstract
A system and method for a computer based system for enabling data phase clock corrections. Basing these corrections primarily on errors that cause consistent phase shift errors while reducing the effect of random data phase errors. An improved phase-locked loop (PLL) is used where multiple data bits are examined simultaneously, allowing us to examine 'apparent future' and 'apparent late' data. The average phase adjustment to the data window is calculated based upon the examined data bits.
