XRS10L140 - SERIAL ATA II: 1:4 PORT MULTIPLIER

General Description

O Serial ATA Output Transmitters.

Key Features

  • such as staggered HDD spin-up, power management control, hot plug capability and support for legacy software. The XRS10L140 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. XRS10L140 meets tight jitter.

PRELIMINARY XRS10L140 SERIAL ATA II: 1:4 PORT MULTIPLIER JUNE 2006 REV. P1.0.2 1.0 INTRODUCTION The EXAR XRS10L140 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 XRS10L140 supports up to 4 SATA drives and utilizes the full bandwidth of the host connection. The upstream ports of XRS10L140 can also be attached to a port selector (XRS10L20) or a Serial ATA Switch to provide redundancy in a more complex topology. The XRS10L140 includes enhanced features such as staggered HDD spin-up, power management control, hot plug capability and support for legacy software.
