Introduction

S3PM9705 is SATA port Multiplier that allows an active host connection to communicate with up to five device ports. S3PM5705 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.

S3PM9705 port multiplier enploys SATA 6.0 Gbps Physical Layer (PHY) technology and recognizes the SATA-defined OOB sequence and speed-negotiation sequence on all of its SATA ports.

It has programmable amplitude and pre-emphasis settings for a range of drive capabilities to support various backplane and cabling environments. The arbiter receives all the requests from the host port, the device ports, and the control port if these ports can transmit a FIS to the host port. The control port has the highest arbitration priority. The priority of the other ports is determined by a fair priority algorithm. All device ports and the host port can be set up through the host port or UART interface to perform SATA self-tests at the same time.
