Abstract
A method for recovering pixel clocks based on an iDP interface includes selecting a prime factor closest to VA or HA from prime factors of X, and selecting a value obtained by subtracting VA from the selected prime factor, as VB, inwhere HA indicates a horizontal active period, HB indicates a horizontal blank interval, VA indicates a vertical active period, and VB indicates a vertical blank interval, fixing the selected VB value, and selecting a total of HB within one frame period and the number of lanes under a condition that Mvid has an integer value, and recovering pixel clocks by multiplying a frequency of link symbol clocks of data received via the lanes by a multiplication of Mvid/48.
