VSC7153
24-PHY 1.5 and 3.0 Gbps SAS Edge/Fanout Expander with
Table Routing and SSP Engine
General Description:
The VSC7153 is a 24-PHY Serial Attached SCSI (SAS) edge/fanout
expander targeted at embedded applications in the midrange and
enterprise storage environments. It offers an attractive technology
upgrade for systems currently employing parallel SCSI technology
with substantial reliance on SCSI-centric applications software or
management solutions. The VSC7153 provides active port
expansion (as defined by the ANSI T10 Serial Attached SCSI 1.0
and 1.1 specifications) for up to 24 connecting PHYs, with
connections made via an internal non-blocking cross-bar matrix.
Programmable output de-emphasis and input signal equalization on
a per-port basis ensure consistent high signal quality in lengthy
backplanes or cable infrastructures. The on-board CPU serves as an
SMP management application client with full in-band SES
enclosure management functions using an integrated SSP virtual
PHY.
Features:
24 SAS Expander PHYs with integrated SerDes
Each PHY can operate independently at 1.5 or 3.0 Gbps
Configurable as a SAS Fanout or Edge Expander
Non-blocking switch architecture (any PHY to any PHY
connectivity)
Table Routing (up to 320 Destination Addresses)
SMP and SSP Virtual PHY with Initiator and Target
Capability
Embedded Enclosure Management Processor (Stanford-1 32
bit RISC) for local control and SES functions
Four operating modes: parallel master, parallel slave, two-wire
serial interface slave, and SPI master modes.
Automatic PHY Speed Detection and Negotiation
Serial ATA Drive support via internal STP/SATA Bridging
Functions (1 per PHY)
Programmable Output De-Emphasis and Input Signal
Equalization Levels
3.3V, 1.8V and 1.2V Power
