Detailed Description
The MAX4888A/MAX4889A high-speed passive switch-
es route PCIe data between two possible destinations.
The MAX4888A/MAX4889A are ideal for routing PCIe sig-
nals to change the system configuration. For example, in
a graphics application, the MAX4888A/MAX4889A create
two sets of eight lanes from a single 16-lane bus. The
MAX4888A/MAX4889A feature a single digital control
input (SEL) to switch signal paths.
The MAX4888A/MAX4889A are fully specified to oper-
ate from a single +3.0V to +3.6V power supply.
Digital Control Input (SEL)
The MAX4888A/MAX4889A provide a single digital con-
trol input (SEL) to select the signal path between the
COM__ and NO__/NC__ channels. The truth tables for
the MAX4888A/MAX4889A are depicted in the
Functional Diagrams/Truth Table section. Drive SEL rail-
to-rail to minimize power consumption.
Analog Signal Levels
The MAX4888A/MAX4889A accept standard PCIe sig-
nals to a maximum of V+ - 1.2V. Signals on the COM_+
channels are routed to either the NO_+ or NC_+ chan-
nels, and signals on the COM_- channels are routed to
either the NO_- or NC_- channels. The MAX4888A/
MAX4889A are bidirectional switches, allowing COM__,
NO__, and NC__ to be used as either inputs or outputs.

MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS AT IC TERMINALS.
OFF-ISOLATION IS MEASURED BETWEEN COM_ AND "OFF" NO_ OR NC_ TERMINAL ON EACH SWITCH.
ON-LOSS IS MEASURED BETWEEN COM_ AND "ON" NO_ OR NC_ TERMINAL ON EACH SWITCH.
CROSSTALK IS MEASURED BETWEEN ANY TWO PAIRS.
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
