The configuration input must be connected to 5V for compatibility with LXT98x or LXT91x-based
designs. The 5V can be supplied from the stacking cable, or a 5V source must exist within the
board itself.
Note:
Stacking boards designed for 5V backplane operation with boards designed for 3.3V backplane
operation causes network errors.

1. The LXT98x and LXT98x0 devices can share the same Inter-Repeater Backplane so long as the proper backplane
buffers are used. Configuration is set to 5V.
2. For LXT98x, LXT91x: The buffer should be the 74ABT245.
For LXT98x0: In the 5V tolerant backplane, the buffer can be either 74ABT245 or 74LVT245
3. Layout follows the same pattern for 10 Mbps operation.
