2.5Gbps PCI Express Passive Switches
/MAX489
General Description
Features
The MAX4888/MAX4889 high-speed passive switches
route PCI Express® (PCIe) data between two possible
destinations. The MAX4888 is a quad single-pole/double-
throw (4 x SPDT) switch ideally suited for switching two
half lanes of PCIe data between two destinations. The
MAX4889 is an octal single-pole/double-throw (8 x SPDT)
switch ideal for switching four half lanes of PCIe data
between four destinations. The MAX4888/MAX4889 fea-
ture a single digital control input (SEL) to switch signal
paths.
♦ Single 1.65V to 3.6V Power-Supply Voltage
♦ Low Same-Pair Skew of 7ps
♦ Low 120µA (Max) Quiescent Current
♦ Supports PCIe Gen I Data Rates
♦ Flow-Through Pin Configuration for Ease of
Layout
♦ Industry-Compatible Pinout
♦ Lead-Free Packaging
The MAX4888/MAX4889 are fully specified to operate
from a single 3.0V to 3.6V power supply and also oper-
ate down to +1.65V. The MAX4888 is available
in a 3.5mm x 5.5mm, 28-pin TQFN package. The
MAX4889 is available in a 3.5mm x 9.0mm, 42-pin TQFN
package. Both devices operate over the -40°C to +85°C
temperature range.

Note 1: Signals on SEL, NO__, NC__ or COM__ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current
to maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

The MAX4888/MAX4889 high-speed passive switches
route PCIe data between two possible destinations. The

Applications Information

DIRECTION
PCIe Switching
The MAX4888/MAX4889 primary applications are aimed
MAX4888
MAX4889
at reallocating PCIe lanes (see Figure 5). For example,
in graphics applications, several manufacturers have
found that it is possible to improve performance by a
factor of nearly two by splitting a single 16-lane PCIe
bus into two 8-lane buses. Two of the more prominent
examples are SLI™ (Scaled Link Interface) and
CrossFire™. The MAX4889 permits a computer mother-
board to operate properly with a single 16-lane graph-
ics card, and can later be updated to dual cards. The
same motherboard can be used with dual cards where
the user sets a jumper or a bit through software to
switch between single- or dual-card operation.
ONE LANE
DATA IS ROUTED
TO EITHER
BOARD A OR B
NOTE: ONLY ONE LANE IS SHOWN FOR CLARITY
Board Layout
High-speed switches require proper layout and design
procedures for optimum performance. Keep design-
controlled impedance PCB traces as short as possible
or follow impedance layouts per the PCIe specification.
Ensure that power-supply bypass capacitors are
placed as close to the device as possible. Multiple
bypass capacitors are recommended. Connect all
grounds and the exposed pad to large ground planes.
