Adlink has released a compact CPU board claimed compliant with version 3.02 of Kontron's ETX “computer-on-module” form-factor spec. The ETX-GLX is based on an AMD Geode LX 800 processor, offers optional HDTV output, supports Linux, and targets applications requiring “a long production life,” the company said.

ETX version 3 added two SATA port connectors to ETX modules while touting full backward compatibility with revision 2.x designs.

Based on the 500 MHz Geode LX 800 processor and CS5536 companion chipset, the 3.7 x 4.5-inch ETX-GLX is supports up to 1 GB of DDR 400 RAM in a single SODIMM socket. Versions are also available that come with either 128 MB or 256 MB of memory soldered directly onto the module.

Adlink says the ETX-GLX supports analog CRT monitors up to a resolution of 1920 x 1440 pixels, and single or dual channel 24-bit LVDS panels at a maximum resolution of 1600 x 1200. It can optionally be equipped with a Focus Enhancements Focus FS 455 TV encoder chip, said to support high-definition TV (HDTV) output at 480p, 720p, and 1080i resolutions.

In accordance with the ETX v3.02 specification, the ETX-GLX features a dual-port SATA controller, along with an EIDE controller that supports both PIO and UDMA modes. The board's Award BIOS provides the ability to redirect video and keyboard data to another system via the serial port, Adlink said.
