The XRS10L210 and XRS10L220 target a wide variety of data storage environments, including data management systems for consumer, industrial and Small Medium Enterprise (SMB) applications.
The XRS10L220 provides the combined advantages of a SATA II port selector and port multiplier implementations at 3.0-Gbit/s and 1.5-Gbit/s. Combining the 4 SATA II PHYs capability on-chip to address two SATA devices with support for a fail-over path from two independent hosts, the XRS10L220 extends the range of high data rate SATA data. Also, in addition to the port multiplier functionality, the XRS10L220 port selector is compliant with SATA II: Port Selector, Revision 1.0.
Exar's XRS10L210 is an active passive SATA-II Host port selector for HA applications that uses redundant SATA host controllers. In addition to supporting side-band and register based switching, the XRS10L210 supports in-band command based switching and is compliant to SATA II: Port Selector, Revision 1.0.
The devices incorporate analog front end with Spread Spectrum Clocking (SSC), reducing the total EMI. The devices also consume under 700mW with several power down modes minimizing power management.
