Product Description: Mini SAS HD receptacle assembly is the next-generation SAS high-density high-speed I/O interface. This interface was adopted for the SAS 2.1 standard and proposed for SAS 3.0 standard, and is designed to support 6G and future 12G SAS applications. The assembly is offered in 4x, 8x, and 16x versions. The reduced size of the Mini SAS HD system provides additional space for system designers. While a low profile PCIe card can accept four 4x Mini SAS connectors, it can only accept two of Mini SAS connectors. The passive Mini SAS HD copper cable assembly is up to 12Gbps data rates per channel. The EEPROM signature enables the host to identify what type and length of cable is connected to its port, and can be customized for any application. An improved latch design reduces the insertion force and increases the retention force.Features: Connector A: SFF-8644 (4x HD Mini SAS) Connector B: SFF-8644 (4x HD Mini SAS) Data Rate: 12Gbps per channel AWG30 Twinaxial 8-pair high-bandwidth low-skew wire Impedance = 100 Ohms Fully compliant to the latest SAS 2.1 AND SAS 3.0 interface specifications Excellent EMI performance Wide operating temperature range: Standard: 0ºC to +70ºC Industrial: -40ºC to +85ºCApplications: DATA Center Servers, Storage racks, RAID systems External Storage Systems SAS/SATA HBA interfaces Direct-attached storage (DAS) Switches
