Section 4 OPERATING INSTRUCTIONS
When the PRBS DATA output is monitored on a sampling oscilloscope using each synchronization output, the following
waveforms are shown:
1) 1/64 CLOCK Shown as an eye pattern.
2) FIXED POSN Shown as a 0 and 1 waveform.
and VAR POSN
At VAR POSN, the synchronization position shifts +16 (or -16) bits each time the PAGE/PATTERN SYNC POSITION
value is incremented (or decremented) by 1.
The above figure is an example. Trigger output at the shown position is not specified.
At FIXED POSN, the position is fixed to 1 of VAR POSN.
