Product Details

The MAX4986 evaluation kit (EV kit) provides a proven design to evaluate the MAX4986 SAS/SATA 2:1/1:2 multiplexer/demultiplexer. The EV kit contains four sections: an application circuit, characterization circuit, and two sets of calibration traces.

The application circuit is designed to demonstrate the MAX4986 in multiplexing and equalizing SAS/SATA signals. This section of the EV kit operates from an external +5V supply that is regulated by an on-board LDO to +3.3V, which powers the MAX4986 (U1). All traces in the application circuit are 100Ω differential controlled-impedance traces.

The characterization circuit is provided for eye diagram evaluation using SMA connectors and 50Ω controlled-impedance traces. This section is powered by an external +3.3V power supply.

For information on the specifications for SATA interfaces, refer to documents defined by the 2.6 release from the Serial ATA industry work group (www.serialata.org), or if superceded, by the most recently released document from the ATA ANSI work group (www.t13.org).
