Sandy Bridge COM Express module offers a bounty of video options

Jan 17, 2011 — by Eric Brown — from the LinuxDevices Archive — 1 views

Advantech announced a COM Express 2.0 Type 6 computer-on-module (COM) based on Intel's new “Sandy Bridge” Core processors and QM67 chipset. The SOM-5890 offers up to 16GB of DDR3 memory — as well as PCIe, SATA3, gigabit Ethernet, and other I/O — and supports display options including VGA, dual-channel 18/24-bit LVDS, SVDO, HDMI, DVI, and Displayport, says the company.

The SOM-5890 joins a number of COM Express modules based on Intel's "Sandy Bridge" Core processors, including Adlink's Express-HR, Congatec's Conga-BM67, Eurotech's Adbc8034, Kontron's ETXexpress-SC, and RadiSys' Procelerant-CEQM67. The SOM-5890 supports one of four newly-revised Core i7 processor models, at up to 2.5GHz, says Advantech (see spec sheet below). The module supports up to 16GB of dual-channel DDR3-1333, and supplies the new Intel QM67 chipset, says the company.

Like the Adlink and RadiSys "Sandy Bridge" COMs, and one of the Kontron devices, the Advantech module features a Type 6 pinout. With Type 6, PCI expansion is sacrificed, but there's the potential for up to three DDIs (digital display interfaces).

As a result, the SOM-5890 provides DisplayPort, HDMI, DVI video interfaces, as well as SVDO, LVDS and VGA output. Expansion takes the form of seven PCI Express (PCIe) x1 lanes and one PEG x16 interface, says Advantech. As with the Adlink Express-HR, the device also offers dual 6Gbps SATA 3 ports, as well as dual 3Gbps SATA 2 interfaces.

The SOM-5890 provides a gigabit Ethernet interface, as well as support for six USB 2.0 ports, says Advantech. Serial and GPIO interfaces are also provided, among others. The 4.92 x 3.74-inch module is said to support temperatures of 32 to 140 deg. F (0 to 60 deg. C).

The SOM-5890 supports Linux and Windows Embedded, says Advantech. The module is also said to ship with the company's Advantech iManager software and related APIs.
