Description
The VSC7177XYI is a Serial ATA and Serial Attached SCSI multiplier/buffer that implements a 2:1 port selector function for 1.5 Gbps and 3.0 Gbps links. It is designed for high availability storage subsystems where redundancy and load sharing are important. This component allows dual hosts, such as I/O controllers, to access single-port disk drives. It provides high output swings, pre-emphasis, and programmable receiver sensitivity needed to drive long backplanes and external cables.
Specifications and features
- 2:1 port selector for both Serial ATA (SATA) and Serial Attached SCSI (SAS) links
- Serial ATA 1.0 compliant at 1.5 Gbps (3.0 Gbps capable)
- Sideband port selection
- Complies with Serial ATA II: Port Selector specification 1.0, including failover control
- Passes Serial ATA patterns transparently
- Programmable receiver sensitivity
- High output swing mode with pre-emphasis
- Compatible with legacy designs (VSC7173 and VSC7175); provides enhanced connectivity and signal pre-emphasis
- 0.6 W to 0.8 W power dissipation (depending on operating mode)
- 3.3 V power supply
- 32-pin, 7 mm x 7 mm QFP-N package
Application Scenarios
- Active-passive redundant failover systems
- Dual-port Serial ATA and Serial Attached SCSI disk arrays (JBODs)
- NAS servers
- RAID subsystems
- Disk-based backup systems
- Serial ATA and Serial Attached SCSI routing applications
- Buffers for externally connected links
Comparison
