ABSTRACT:
A stabilized frequency oscillating circuit outputs a pixel clock signal to an image scanner for controlling pixel rate at various writing positions along a scan line. The circuit includes a synchronization circuit having a first control signal component output to adjust a nominal output frequency of the oscillator; and a frequency profiling circuit having a second control signal component output which varies as a function of writing position along the scan line to determine a corrected output frequency of the oscillator which varies as a function of writing position along the scan line.
