• Compliant with SAS-2.1 and SPL specifications
• Supports multi-rate operation at 1.5, 3.0, and 6.0 Gbps
• Provides 44-port PHY expansion capabilities

Applications

• Enterprise storage area networks (SAN)
• High-density disk enclosure backplanes
• Data center storage infrastructure

Procurement Notes

Verify the exact suffix and package type against the manufacturer's current documentation. Confirm that the component status is acceptable for your design lifecycle, as availability may vary for older generations. Ensure compatibility with your system's voltage requirements and interface protocols before procurement.

Selection Notes

Select this component when designing SAS-based storage systems requiring extensive port expansion. Evaluate thermal management needs due to high PHY counts. Verify that the host controller supports the required SAS protocol versions for seamless integration into the storage topology.

Part Context

This part belongs to the Maxim Integrated SAS expander family, specifically designed for expanding SAS connectivity in enterprise environments. It serves as a critical interconnect solution for managing multiple drives within complex storage architectures.

Replacement Considerations

Check for newer generation SAS expanders from Analog Devices or Maxim Integrated that offer higher port counts or improved power efficiency. Verify pin-to-pin compatibility if substituting directly.
