Description

The 88SX7042-B0-BDU1C000 is an electronic component model in the IC Chips product category. It is a Serial ATA (SATA) Port Multiplier that allows an active host connection to communicate with up to four device ports and one SEMB port. This port multiplier consolidates the capacity of storage devices by enabling a single host SATA port to be connected to multiple SATA devices. It utilizes Marvell's SATA 3.0 Gbps Physical Layer (Phy) technology.
