A comparator generates the horizontal synchronizing signal at a time when a count value output from the clock counter becomes equal to a synchronization counter value. A synchronization counter value output section generates the synchronization counter value by performing addition/subtraction in each of scanning lines based on a basic counter value. | 01-12-2012 |
20130002954 | CLOCK GENERATION METHOD AND APPARATUS IN MULTIMEDIA SYSTEM - A clock generation method and apparatus in a multimedia system includes generating a first intermediate clock with multiple phases by multiplying a frequency of an input clock by a predetermined factor using a phase-locked loop or a delay-locked loop, generating a transmission clock by dividing a frequency of the first intermediate clock by 5, and generating a pixel clock used in the multimedia system using a frequency of the transmission clock. When the first intermediate clock with the multiple phases is used to generate the pixel clock corresponding to a color depth, the number of phase-locked loops or delay-locked loops necessary for frequency multiplication can be reduced. | 01-03-2013 |
