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.
