DE4-FOX PMC Mezzanine Module

SATA Controller & 1.8-Inch Solid State Drive (SSD)

The DE4-FOX is a PMC style single-width mezzanine card, equipped with a quad-channel PCI to SATA controller, and one or two 1.8-inch Micro SATA solid state drives (SSD) or hard disk drives. In addition to the on-board drive(s), another two SATA channels can be used for attachment of external SATA storage devices, either through the front bezel connectors (eSATA type), or via rear I/O (across the P14 connector to a suitable host carrier board).

As of current, suitable on-board mounting Micro SATA solid state drives are available with 64GB and beyond storage capacity, delivering sufficient space for installation of any popular operating system.

A single drive will be mounted on the component side (side 1) of the mezzanine card (facing the carrier board when module is engaged). As an option, a second drive can be accommodated on the back side (module side 2, on top of the stack when mezzanine card is engaged).

Flash technology based SATA drives, both SLC and also MLC architecture, provide significant advantages compared to rotating memory solutions (aka hard disk), e.g. less power consumption, faster data I/O transfers, lower latency time, industrial temperature grade and superior immunity against shock and vibration.

The DE4-FOX can accommodate one or even two 1.8-inch microSATA standard form factor drive(s) according to the SFF-8144 specification, which results in a 5.0 mm maximum height, and 78.5mm x 54.0mm dimensions.

Due to the cutout area of 72mm x 48mm in the DE4-FOX PCB, which exactly matches the profile of an SFF-8144 compliant device, the 1.8-inch drive will be fixed in all 4 directions. In addition, a mounting frame is used to hold each drive, for extremely rugged applications.
