1:2 eSATA port multiplier targets data storage environments

Fremont, Calif. — Exar expanded their EXstor SATA port multiplier family with the addition of the 1:2 eSATA port multiplier device. This design targets data storage environments including data management systems for consumer, industrial and small medium enterprise (SME) applications.

The XRS10L120 supports the latest Serial ATA II port multiplier specifications, enabling up to two SATA Gen I and Gen II drives to be connected to a single SATA or SAS host bus adaptor. The device supports two eSATA ports, which is suitable for digital video recorder (DVR) applications and other consumer applications requiring a SATA host to support two ports—one connecting to an internal drive and the other port connected to an external drive through eSATA. The device supports 3.0 Gbits/s and 1.5 Gbits/s data rates. In addition, the device consumes less than 750 mW and supports several power-down modes, programmable output swing and transmit/receive equalization. The XRS10L120 supports spread spectrum clocking (SSC), which lowers the system electromagnetic interference (EMI) and helps eliminate the need for a metal shield to block EMI. The design has a built-in, self-test pattern generator and checker and line/internal loop back modes of operation plus other diagnostic capabilities. The device also supports SATA compliant out of band (OOB) signaling—detection, transmission and handshaking and control state machine with optional bypass modes.
