Patent ID: 7852510

Claim:
A data-processing system, comprising: a rendering device which renders documents based upon the timing and duration of a laser beam associated with particular pixel data; a laser driver that is responsive to said pixel data in order to activate said laser beam from a laser element; a controlling mechanism for controlling and adjusting said particular pixel data, wherein said controlling mechanism is subject to pixel clock signal in order to optimize a performance of said rendering device under varying rendering parameters and thereby enhance the quality of data rendered via said rendering device, wherein said controlling mechanism comprises a programmable phase locked loop circuit to which a pixel clock signal and a frequency of said pixel clock signal are applied in order to generate at least one output signal for controlling said laser beam; a pin associated with said controlling mechanism and for adjusting said frequency of said pixel clock signal; a dividing circuit for receiving said output signal from said programmable phase locked loop circuit to produce an output clock signal; a delay circuit for producing a delayed pixel clock signal wherein said delay circuit is associated with, and communicates electronically with, said dividing circuit; at least one parallel-to-serial converter circuit associated with said controlling mechanism, wherein video data is applied to said at least one parallel-to serial converter in order to generate an output signal thereof and wherein at least clock signal is applied to said at least one parallel-to-serial converter, such that said at least one clock signal is faster than said pixel clock signal in order to control a maximum duration of said output signal; and a plurality of override circuits coupled to said at least one parallel-to-serial converter circuit for outputting data in the form of sub-pixel data.
