MAX14970

Ruggedized 6Gbps SATA Redriver with High

ESD and Extended Temperature Operation

General Description

Beneﬁts and Features

The MAX14970 dual-channel buffer with input equaliza-

tion and preemphasis is ideal to redrive internal serial-ATA

(SATA) 1i, 2i, and 3i signals as well as eSATA 1m and 2m

signals. The device features high electrostatic discharge

(ESD), ±8kV Human Body Model (HBM) protection. The

device can be placed near a SATA connector on the moth-

erboard to overcome board losses and guarantee SATA

compliance. The device is SATA specification version 3.0

(gold standard) compliant and can also be pin configured for

SATA specification version 2.6 (gold standard) compliance.

● Robust Solution for Harsh Environments

• Extended Temp Rating: -40°C to +85°C

• High ESD Protection on All Pins: ±8kV (HBM)

• TQFN (4mm x 4mm) Package for Resistance to

Vibration/Shocks

● Unique Power-Saving Design

• Standby State: <1mW (typ)

• Dynamic Power-Down State

Idle State: 52.8mW (typ)

Active State: 231mW (typ)

The device features hardware SATA-drive cable detection

that automatically places the device into a standby mode

that consumes less than 20µA (typ) standby current when

no drive is connected. In addition, the device features an

independent channel dynamic power-down mode where

power consumption is reduced when no input signal is

present. The device maintains output common-mode

levels to meet internal SATA version 3.0 standards and

prevent delays when coming out of low-power mode.

● Design Flexibility

• Input Equalization and Selectable Output

Preemphasis

• Single 3.3V Supply Operation

• SATA 3i (6.0Gbps), SATA 2i/2m (3.0Gbps),

and SATA 1i/1m(1.5Gbps) Compatible

Applications

● Industrial/Embedded PC

● Portable IPC/HMI

● Industrial Server

● Medical

The device preserves signal integrity at the receiver by

reestablishing full output levels and reducing the total sys-

tem jitter (T ) by providing equalization. The device fea-

tures channel-independent digital preemphasis controls

to drive SATA outputs over longer trace lengths to meet

internal SATA specifications. SATA out-of-band (OOB)

signaling is supported using high-speed out-of-band

signal detection on the inputs, and squelch on the cor-

responding outputs. Inputs and outputs are all internally

50Ω terminated and must be AC-coupled to the SATA

controller IC and SATA device.

● SATA SSDs or HDDs

Ordering Information appears at end of data sheet.

The device operates from a single +3.3V (typ) supply, is

available in a small, 4mm x 4mm TQFN package with flow-

through traces for ease of layout, and is specified over the

extended -40ºC to +85ºC operating temperature range.
