88SM4140 datasheet

Description :

The Marvell 88SM4140 port multipier device offers the industry's first solution for port expansion.

The 88SM4140 is a Serial ATA (SATA) Port Multiplier (PM) that allows an active host connection to communicate with up to four device ports and one SEMB port. The 88SM4140 is used to consolidate the capacity of storage devices by allowing a single host SATA port to be connected to more than one SATA device. This port multiplier employs Marvell’s SATA 3.0 Gbps Physical Layer (Phy) technology.
