Abstract:
A medical imaging system includes a video interface connecting different medical imaging modalities to a laser printer. The video interface includes a clock recovery phase-lock-loop (PLL) as a frequency synthesizer video signal from a modality. A second PLL inserts a pulse train equal to the horizontal frequency into an analog video signal having a vertical sync interval with no serrating pulses. This assures the clock recovery PLL will maintain lock during the vertical sync interval.
