Up to 8.0Gbps Dual Passive Switches

General Description

Features

The MAX4888B/MAX4888C dual double-pole/double-

throw (2 x DPDT), high-speed passive switches are

S Single +3.3V Power-Supply Voltage

S Supports PCIe Gen I, Gen II, and Gen III Data

ideal for switching two half-lanes of PCI Express (PCIe)

Rates

data between two possible destinations. These devices

feature a dual digital control input to switch signal paths.

The MAX4888C is intended for use in systems where

both the input and output are capacitively coupled (e.g.,

SAS, SATA, XAUI, and PCIe) and provides a 10FA (typ)

source current and a 60kI (typ) internal biasing resistor

to GND at the AOUT_ and BOUT_ pins.

S Supports Up To and Including 6.0Gbps SAS/SATA

Signals

S Supports Other High-Speed Interfaces (e.g., XAUI)

S Superior Bandwidth Return Loss

S Small, 3.5mm x 5.5mm, 28-Pin TQFN Package

The devices are fully specified to operate from a single

+3.3V (typ) power supply. Both devices are available

in an industry-standard 3.5mm x 5.5mm, 28-pin TQFN

package. They operate over the -40NC to +85NC extend-

ed temperature range.
