EVAALVUAAILTAIOBNLEKIT

Dual 1.5/3.0/6.0Gbps SAS/SATA Redriver

General Description

The MAX4952B dual-channel redriver is designed to

redrive one full lane of SAS or SATA signals up to

6.0Gbps and operates from a single +3.3V supply.

The MAX4952B is designed for commercial SAS or

SAS/SATA applications, such as servers.

The MAX4952B features independent output boost and

enhances signal integrity at the receiver by re-establishing

full output levels. SAS and SATA out-of-band (OOB)

signaling are supported using high-speed amplitude

detection on the inputs and squelch on the correspond-

ing outputs.

Inputs and outputs are all terminated in 50I internally

and exhibit excellent return loss.

The MAX4952B is available in a small, 20-pin, 4.0mm x

4.0mm TQFN package with flow-through traces for ease

of layout. This device is specified over the 0NC to +70NC

operating temperature range.
