MAX4951 - SATA I/SATA II Bidirectional Re-Driver

General Description

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-compatible signal level.

Key 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) supply and is available in a small, 4mm x 4mm, TQFN package with flow.

19-4178; Rev 0; 6/08 www.DataSheet4U.com SATA I/SATA II Bidirectional Re-Driver General Description 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-compatible signal level. The MAX4951 preserves signal integrity at the receiver by reestablishing full output levels, and can reduce the total system jitter (TJ) by squaring up the signal. This device features channel-independent digital boost controls to drive SATA outputs over longer trace lengths, or to meet eSATA specifications.
