Interconnect system targets high-speed SAS, SATA apps

Molex Inc. has announced the development of its new iPass Interconnect System that will support the higher density requirements of Serial Attached SCSI (SAS) and Serial ATA (sata) high-speed, multi-lane internal and external systems.

The iPass System includes host board and backplane connectors as well as cable assemblies for applications including host bus adapters (hbas), controller cards, servers, storage racks, switches, redundant array of independent discs (RAID) controllers, and Just a Bunch of Disks (JBODs) enclosures.

The complete offering supports SAS and SATA speeds ranging from 1.5Gbps to 6Gbps, with a capability up to 10Gbps, allowing OEMs and integrators to provide systems with the interconnect granularity and bandwidth that eliminates the need to invest in new connectors for future generations of products. In addition, users do not have to test and qualify two different families of connectors because the mating interface is the same for both internal and external applications, which also reduces cost.

The iPass Interconnect System for external system applications include:

&149; SMT host connector: The SMT design enables placement on both sides of the PC-board for increased port density. With a pitch of 0.08mm, the design also allows for easy routing of traces on the circuit board, and standoffs allow for easy PC-board cleaning after soldering. In addition, the basic connector interface has been tested for speeds up to 10Gbps.

&149; EMI guide frame assembly: The Guide Frame is available in one-by-one, one-by-two, and one-by-four configurations. It provides the robust mechanical structure required to keep the stresses induced from large, heavy cables separate from the connector interface. The die cast construction features screw attachment to the host board to support the weight of large diameter cables, and an EMI gasket seals the guide to the system bezel. The guide also provides rugged cast-in keys to support both SAS and SATA requirements.

&149; 4X external cable assembly: Its high performance paddle-card design with impedance matching helps reduce crosstalk and provide improved signal integrity for storage system applications. The assembly also features a flexible, low-profile, latch-pull mechanism that is easily accessible in high-density applications. The reduced size plug supports double the number of ports in the same space as the current SFF-8470 solution. An EMI gasket seals the plug to the guide interface and key slots are provided to mate with the guide keys according to the appropriate standard.

The internal version of the iPass Interconnect System includes:

&149; Right angle and vertical SMT host connector with hood kit: This 0.80mm pitch connector includes a hood kit for internal applications. Acting as a disposable pick-and-place cap, its pre-positioning device aligns the connector to the hood for consistent robotic pick and placement. Retention-fit and SMT PC-board mounting options are available on the hoods to accommodate a variety of circuit board assembly processes. Custom keying is also available. The kit comes with tape and reel packaging for robotic processing.

&149; Internal cable assemblies: Delivering up to four times the port density of the current 4X offering, the overmolded internal cable assemblies have a direct-attached wire termination. In addition to iPass-to-iPass cable assemblies, transition cables are available to legacy SFF-8484 4x multi-lane connectors, 1x SATA style connectors and to both SAS and SATA disk drive connectors. The cable assemblies provide 100-ohm differential impedance with tight skew control and low cross talk. Several cable lengths are offered as standard products. Custom lengths are available. The 36-circuit iPass assembly includes up to eight sidebands to support enclosure management functions and to support control lines for SAS applications.

The iPass Interconnect System has been approved for use in both the T10/SAS standard, and the SATA IO Organization, and is documented in the SFF Committee standards (SFF-8086, SFF-8087 and SFF-8088).

The system is currently offered in limited quantities and will be available for full release in Fall 2005. Pricing information is not available at this time.
