This manual provides information on the SY89831U
evaluation board. It should be used in conjunction with the
SY89831U datasheet, which contains full specifications of
the SY89831U.
The SY89831U evaluation board enables fast and
thorough evaluation of the SY89831U fanout buffer/
translator. The board is designed in multiple layers for better
performance and simpler signal evaluation.

1. Connect power; a single power supply is used.
Connect BP1 (VCC) to +3.3V. Connect BP2
(GND) binding post to supply ground. See
SY89831U datasheet for power supply range.
2. Set SW2 to enable device.
a. Set switch 2 off to enable device.
b. Switch 1 has no effect on operation.
3. Set signal generator for appropriate output swing
amplitude, data rate and bit pattern, as allowed
by the SY89831U datasheet. There is no need to
set DC-offset as the board is AC-coupled. Ensure
the signal generator is capable of driving
AC-coupled loads. The SY89831U evaluation
board does not provide 50Ω source termination
resistors.
SETUP FOR MEASUREMENTS (FIGURE 2)
4. Connect desired SY89831U outputs to the
oscilloscope. Unused outputs of a switching pair
must be terminated. Ensure the oscilloscope is
triggered properly. The oscilloscope must have
internal 50 terminations to ground. ChooseΩ
desired measurements on oscilloscope.
a. Please refer to oscilloscope’s manual for eye
pattern, total jitter and rise/fall measurements.
b. For BER testing, feedback an output to the
BERT data input. After resetting the error
count, the error count should remain zero. See
BERT manual for more details.
