SATA I/II Bidirectional Redriver

with High ESD and Cable Detect

General Description

Features

The MAX4951AE dual-channel buffer is designed to

redrive serial-ATA (SATA) I and SATA II signals and

can survive ESD events up to Q8kV Human Body Model

(HBM). The MAX4951AE can be placed near an eSATA

connector to overcome board losses and produce an

eSATA-compliant signal level. This device is Serial ATA

Revision 2.6 (gold standard)-compliant, while overcom-

ing losses in the PCB and eSATA connector.

S Single +3.3V (typ) Supply Operation

S Low-Power, 350µA (typ) eSATA Cable Detect

S Supports SATA 1.5Gbps and 3.0Gbps Data Rates

S Meets SATA I, SATA II Input/Output-Return Loss

Mask

S Exceeds eSATA Standard Compliant Eye Mask for

Jitter

The MAX4951AE features low standby current for power-

sensitive applications. This device features hardware

SATA-drive cable detection, keeping the power low in

standby mode.

S Meets or Exceeds eSATA Standard Compliant Eye

Mask for Output Levels

S Supports SATA OOB Signaling

S Internal Input/Output 50I Termination Resistors

S Inline Signal Traces for Flow-Through Layout

S Pin Compatible with MAX4951

The MAX4951AE preserves signal integrity at the receiv-

er by reestablishing full output levels. It reduces the total

system jitter (T ) by squaring up the signal and providing

excellent return loss match to the source. This device

features channel-independent digital boost controls

to drive SATA outputs over normal trace lengths and

eSATA connector. 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 50I terminated.

S Space-Saving, 4mm x 4mm, TQFN Package

S ESD Protection on All Pins: ±±kV (HBM)
