7. Application/Implementation

7.1 Reference Schematic

•

Determine the loss profile between a transmitter and a receiver.

•

Based upon the loss profile and signal swing, determine the optimal equalization settings.

•

Select appropriate voltage output swing.

•

If required, select the correct differential pair polarity.

•

To set voltage logic levels on configuration pins, use a 5-kΩ pullup for high level, tie pin to GND for low level,and place a 5-kΩ

pullup and 5-kΩ pulldown for HiZ.
