FEATURES
GENERAL
• Flexible 24-port SAS Expander device
• Virtual SSP target/initiator port
• Low-latency connection arbitration
• Supports table routing of 1024 entries,
direct routing and subtractive routing
• Integrated a non-blocking cross bar
switch allowing any-port to any-port
connections
• Arbitrary SAS wide port configurations
• STP bridge function allows either SAS
or SATA target devices to be attached
to any port
• Integrated RISC processor for SAS
SMP functions and SES support
• Three configurable multi-master or
slave mode TWI interfaces for device
configration and control of external
interfaces
• UART interface for debugging support
• SFF-8485 compliant Serial GPIO
(SGPIO) interface provides expansion
for up to 144 GPIOs
HIGH-SPEED I/O
• 1.5 Gbit/s and 3.0 Gbit/s operation
• Automatic negotiation of link speed
• Accepts Spread Spectrum Clocking
(SSC) from SATA HDDs
• Programmable transmit pre-emphasis
and receiver equalization
• Programmable transmit output swing
to support both SATA and SAS levels
• Integrated resistive termination and
receiver AC coupling
STATISTICS & PERFORMANCE
MONITORING
• Per-port error counters to provide
comprehensive diagnostic functions
