Datasheet
Document #: 248987
Revision#: 003
Rev Date: 08/07/01
4.4.1
Local Backplane
—
3.3V Only
The LXT98x0 local backplane operates at 3.3V only. LXT98x and LXT91x devices operate at 5V.
LXT98x0 devices are, therefore, not cascadable with LXT98x and LXT91x devices.
Note:
Do not mix LXT98x0 with either LXT98x or LXT91x devices on the local backplanes.
4.4.2
Stack Backplane
—
3.3V or 5V
The LXT98x0 stack backplanes can be configured to be either 3.3V or 5V. COMP_SEL (Pin 39), a
special input pin, selects between the two voltage modes, depending on whether 3.3V or 5V is
applied.
3.3V-Only Stacks
Apply 3.3V to COMP_SEL, IR100CFSBP, IR10CFSBP, and
IR10COLBP for LXT98x0 backplane operation
For 5V Backwards
Stackability
Apply 5V to COMP_SEL, IR100CFSBP, IR10CFSBP, and IR10COLBP
for LXT98x and LXT91x backplane operation.
With either mode (3.3V or 5V), COMP_SEL draws less than 3 mA.
Note:
1. The external pull-up resistor values remain the same, regardless of 3.3V or 5V backplane
operation.
2. The recommended digital signal external buffer has been changed to 74LVT245 for the
LXT98x0.
4.4.2.1
3.3V and 5.0V Stacking Boards Cannot Be Mixed
3.3V Operation
Boards designed for 3.3V backplane operation should only be stacked with other 3.3V boards.
Existing LXT98x or LXT91x based designs cannot operate in 3.3V.
Incompatible Stacking
Configurations
A LXT98x0-based board configured for 3.3V backplane operation and LXT98x or LXT91x
based boards (5V only).
A LXT98x0-based board configured for 3.3V backplane operation and a LXT98x0-based
board configured for 5V backplane operation.
The following stacking configurations are incompatible:
Note:
Stacking boards designed for 3.3V backplane operation with boards designed for 5V backplane
operation causes network errors.
5V Operation
Boards designed for 5V backplane operation should only be stacked with other 5V boards:
LXT98x or LXT91x-based designs.
LXT98x0 designs configured for 5V backplane operation.
