I have a scanning instrument that makes an HSYNC (500ms period), VSYNC (500usec period, phase locked to the line frequency, 60hz), and four video signals without timing information. No pixel clock is available. I would like an image that is roughly 1024x800 pixels
I have pulled the W1 jumper to use differential mode for ground loop noise immunity.
Can I use the External Lock Line Scan Camera mode if I strap PCLKOUT to PCLKIN? I am unsure whether to strap +- to +-, + to + with - to - to gnd, or pclkin - to gnd and pclkout- open circuit. Obviously I don't want to gnd pclkout - if both pclkout+- lines are driven by low impedence amplifiers.
And what are the output impedences of such amplifiers?
Is pclkout capable of driving
a 75ohm sink?
Will pclkout be phase locked to HSYNC?
