The Analog Devices MAX4951AECTP+ is a single-channel Buffer, ReDriver IC designed specifically for eSATA applications. It operates from a 3V to 3.6V supply, drawing 75mA, and supports data rates up to 3Gbps with a propagation delay of 240ps.
No official second source is listed, so dual-sourcing would require a pin-compatible alternative from a different vendor — none is documented in the manufacturer's cross-reference.
The suffix 'T' typically denotes tape-and-reel packaging. The MAX4951AECTP+ (no T) ships in tray format. The die and electrical specs are identical.
The part is specified for eSATA applications. While the electrical interface is similar, eSATA has different cable-loss and signal-level requirements than internal SATA. The 3Gbps data rate covers SATA 3.0, but the equalization and output swing are tuned for eSATA cable runs. For internal SATA, a part specified for that application would be a safer fit.
