Patent ID: 8400567

Claim:
A method for recovering pixel clocks based on an iDP (Internal Display Port) interface, the method comprising: selecting a prime factor closest to VA or HA from prime factors (X), and selecting a value obtained by subtracting VA from the selected prime factor, as VB, in Mvid = ( HA + HB ) × ( VA + VB ) X , where 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 (M value of M/N PLL) 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.
