The MAX4951C 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) Q8kV Human Body Model (HBM) pro-

tection. The device can be placed near a SATA connec-

tor on the motherboard to overcome board losses and

guarantee SATA compliance. The device is SATA speci-

fication version 3.0 (gold standard) compliant and can

also be pin-configured for SATA specification version 2.6

(gold standard) compliance.

The device features hardware SATA-drive cable detec-

tion that automatically places the device into a standby

mode that consumes less than 20FA (typ) standby cur-

rent 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.

The device preserves signal integrity at the receiv er by

reestablishing full output levels and reducing the total

system jitter (T

features channel-independent digital preemphasis con-

trols 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 corresponding outputs. Inputs and outputs are all

internally 50I terminated and must be AC-coupled to the

SATA controller IC and SATA device.

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 commercial 0NC to +70NC operating temperature

range. The MAX4951C is also pin compatible with the

MAX4951BE SATA 6.0Gbps redriver.
