MAX4951

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 (T_J) 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. 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-through traces for ease of layout. This device is specified over the 0°C to +70°C operating temperature range.
