XRS10L120 - SERIAL ATA II: 1:2 PORT MULTIPLIER

Description

The EXAR XRS10L120 is a Serial ATA port multiplier designed for next generation enterprise class disk array systems that use SATA mid-planes.

The device is targeted at low cost storage applications.

This function is used when one active host has to communicate with multiple SATA drives.

Features

  • such as staggered HDD spin-up, power management control, hot plug capability and support for legacy software. The XRS10L120 acts as a retimer, maintaining independent signaling domains between the drives themselves and the external interconnect. The high-speed serial input features selectable equalization adjustment and the high-speed serial output features selectable pre-emphasis to compensate for ISI (Inter-Symbol Interference) and increase maximum cable distances. XRS10L120 meets tight jitter.

PRELIMINARY XRS10L120 SERIAL ATA II: 1:2 PORT MULTIPLIER DECEMBER 2006 REV. P1.0.1 GENERAL DESCRIPTION The EXAR XRS10L120 is a Serial ATA port multiplier designed for next generation enterprise class disk array systems that use SATA mid-planes. The device is targeted at low cost storage applications. This function is used when one active host has to communicate with multiple SATA drives. The XRS10L120 supports up to 2 SATA drives and utilizes the full bandwidth of the host connection. The upstream ports of XRS10L120 can also be attached to a port selector (XRS10L210) or a Serial ATA Switch to provide redundancy in a more complex topology.
