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.
