Dual-channel buffer from Maxim redrive SATA I/ II with cable detect and high ESD

Maxim has introduced the MAX4951AE, a new dual-channel buffer that redrive SATA I and SATA II signals and can survive ESD events up to ±8kV Human Body Model (HBM). The MAX4951AE buffer is suitable for the applications such as notebook computers, docking stations, data storage/work stations, desktops and servers.

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 overcoming losses in the PCB and eSATA connector.

MAX4951AE preserves signal integrity at the receiver by reestablishing full output levels. It reduces the total system jitter (TJ) by squaring up the signal and providing better return loss match to the source.

The key features of the MAX4951AE buffer are,

Single operating input voltage is +3.3V (typ)
Low-power, 350µA (typ) eSATA cable detect
Supports SATA 1.5Gbps and 3.0Gbps data rates
Meets SATA I, SATA II input/output-return loss mask
Exceeds eSATA standard compliant eye mask for Jitter
Supports SATA OOB signaling
Internal input/output 50-Ohm termination resistors
Inline signal traces for flow-through layout
Space-Saving, 4mm x 4mm, TQFN Package

The MAX4951AE also features low standby current for power-sensitive applications. This device features hardware SATA-drive cable detection, keeping the power low in standby mode.

Operating temperature range from 0°C to +70°C

Package: 4mm x 4mm, 20-pin TQFN package
Price: Starts at $1.50 for 1k pieces
