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.
