Maxim Introduces the MAX4951AE, a Dual-Channel Buffer to Redrive SATA I and SATA II Signals

The MAX4951AE is a dual-channel buffer designed to redrive SATA I and SATA II signals. This device preserves signal integrity at the receiver by reestablishing full output levels, and it can reduce total system jitter (TJ) by squaring the signal. By redriving signals on both the transmit and receive channels, the device supports SATA I and SATA II data rates (up to 3.0Gbps). The MAX4951AE is designed for applications such as notebook computers in which the user needs to push the signal through docking-station connectors, onto a mezzanine board, and through an external connector while being compliant with the SATA v3.0 specification. It is also well suited for desktops and servers that must carry signals over long cables and boards while overcoming losses on the PCB and in the eSATA connector. The MAX4951AE is the only eSATA/SATA redriver in the industry that can enter a low-power standby mode when the integrated cable-detect pin is either pulled high or left unconnected. This capability reduces the supply current significantly and conserves power in mobile environments such as notebooks and netbooks…
