Preliminary Data Sheet

Distance: Number of pixels in system clocks X1/CLK2 between two output H-Syncs

time to close = time(field) * number of active pixels / (distance/512)

e.g. time to close = 10 ms * 720 / (864/512) = 4,26 s

time to close = time(field) * number of active pixels / (pplop/128)

Output write parameter: WINDVSP

LPFIP: Lines per field of the input signal - amount of lines between two input V-Syncs

time to close = time(field(interlaced)/frame(progressive)) * number of active lines / (lpfip/256)

e.g. time to close = 10 ms * 576 / (312/256) = 4.7 s

time to close = time(field) * number of active lines / (lpfop/128)
