VSC7155VU-02

Overview

The VSC7155VU-02 is a multimode, user-configurable 18-PHY Serial Attached SCSI (SAS) expander designed for edge and fanout topologies. It supports SAS port expansion as defined by ANSI T10 specifications for both 1.5Gbps and 3.0Gbps speeds. The device features an internal nonblocking cross-bar matrix enabling any PHY to any PHY connectivity. It includes 18 integrated serializer/deserializers (SerDes), per-PHY diagnostics, retiming elasticity buffers, and an embedded Stanford-1 32-bit RISC CPU for enclosure management.

Feature Summary

Supports up to 18 independent PHYs operating at 1.5Gbps or 3.0Gbps with automatic speed detection and negotiation.
Features a nonblocking switch architecture allowing flexible connection between any input and output ports.
Includes an embedded enclosure management processor compatible with SES functions and serial I²C interfaces.
Provides programmable output deemphasis and input signal equalization to maintain signal integrity across backplanes.

Applications

Blade servers
JBOD arrays
Enterprise storage environments
Rack-mounted servers with RAID

Procurement Notes

Verify the current status of the VSC7155VU-02 before procurement planning. The datasheet indicates this component is designated as Last Time Buy. Confirm availability through authorized distributors and check for potential discontinuation notices from Analog Devices or Maxim Integrated to ensure long-term supply chain stability.

Selection Notes

Select the VSC7155VU-02 for systems requiring high-density SAS expansion in midrange or enterprise storage. Ensure compatibility with existing parallel SCSI software or management solutions if migrating from legacy architectures. Evaluate the need for STP/SATA bridging capabilities and verify that the BGA package fits the target PCB layout constraints.

Part Context

This part belongs to the VSC7155 series of SAS expanders manufactured by Analog Devices Inc./Maxim Integrated. It serves as a hardware solution for distributing SAS signals to disk drive arrays in servers or external enclosures. The device integrates multiple I/O interfaces and general-purpose I/O including SGPIO for comprehensive system control.

Replacement Considerations

Check for updated product announcements from Analog Devices regarding successors to the VSC7155 series. Verify pin-to-pin compatibility and firmware support when considering alternative SAS expanders for new designs.
