DISP OUT:
Amplitude: +4.5 1 V
Pulse Width: 0.3 to 1.0 μs
Timing:
For ISLS disparity, the pulse occurs 65 1 μs after the
enable trigger.
For Mode 4 Word B disparity, the pulse is coincident with
the pulse at 19 1.0 μs.
For Mode 4 Word A, the pulse occurs 198 2 μs after the
enable trigger.
ISLS disparity takes precedents over Word A or B
disparity
