The MAX4951 dual-channel buffer is designed to re-drive

serial-ATA (SATA) I and SATA II signals and is functional

up to 6.0Gbps for next-generation data rates. The

MAX4951 can be placed near an eSATA connector to

overcome board losses and produce an eSATA-compati-

ble signal level.

The MAX4951 preserves signal integrity at the receiver by

reestablishing full output levels, and can reduce the total

system jitter (T

features channel-independent digital boost controls to

drive SATA outputs over longer trace lengths, or to meet

eSATA specifications. SATA Out-Of-Band (OOB) signaling

is supported using high-speed amplitude detection on the

inputs, and squelch on the corresponding outputs. Inputs

and outputs are all internally 50Ω terminated and must be

AC-coupled to the SATA controller IC and SATA device.

The MAX4951 operates from a single +3.3V (typ) sup-

ply and is available in a small, 4mm x 4mm, TQFN

package with flow-through traces for ease of layout.

This device is specified over the 0°C to +70°C operat-

ing temperature range.
