The SFF-8643 is the latest HD MiniSAS connector design for implementing HD SAS Internal interconnect solutions.
The SFF-8643 is a 36-pin ‘High Density SAS’ connector, and utilizes a plastic body typically used in internal connections. Typical application would be a INTERNAL SAS link between a SAS HBA to SAS drives.
The SFF-8643 is compliant with the latest SAS 3.0 spec, and supports 12Gb/s data transfer protocol
The SFF-8643’s HD MiniSAS external counterpart is the SFF-8644 which is also SAS 3.0 compliant, and also supports 12Gb/s SAS data transfer speeds.
Both the SFF-8643 and the SFF-8644 can support up to 4-ports (4 lanes) of SAS data.
CS Electronics has incorporated this connector onto both cable assemblies and pcb adapters.
These newer SFF-8643 and SFF-8644 HD SAS connector interfaces have essentially replaced the older SFF-8088 external and the SFF-8087 internal SAS interfaces, however CS Electronics continues to support our customers’ needs for the older interface cables and adapters.
