Concurrent Unveils Dual 1600x1200 CRT/DFP Graphics PMC Adaptor

2/16/2004 - Concurrent Technologies announces the latest addition to its range of graphics PMC mezzanine cards. The IO PMC/731 is a dual 1600x1200 graphics adaptor with analog RGB (to CRT) and digital flat panel (DFP) outputs. The IO PMC/731 is one of the industry's first PMC adaptors to support DFP resolutions up to 1600x1200. Plus, both CRT and DFP outputs can be driven simultaneously with either different images or resolutions. Each output is available via a front panel DVI-I connector and the DFP PanelLink® output is also accessible via the P4 rear panel. The DFP interface cable can be up to 5 meters in length. The IO PMC/731 can be used with Concurrent Technologies' CompactPCI® and VME or any other PMC compliant host board.

The adaptor uses Silicon Motion's SM731, an embedded 3D/2D dual display controller, supporting resolutions up to 1600 x 1200. The CRT refresh vertical scan rate is up to 85Hz and the DFP data refresh rate is 60Hz. The SM731, a 128-bit graphics engine, also provides an integrated 24-bit RAMDAC which supports output pixel rates of up to 235MHz. High resolution and high performance users will benefit from the 16 Mbytes of on-chip 150MHz SGRAM to provide ample local storage for image and off-screen data such as texture maps, Z-buffer, and backing store. Included is the capability to perform 90, 180 and 270 degree hardware rotation. The graphics engine implements, in hardware, full acceleration of graphics functions and BitBLTs.

The IO PMC/731 is a single-size card and is compliant with the CMC (Common Mezzanine Card) specification. The board complies with the PCI specification and features a PCI 33MHz 32-bit interface using 3.3V signaling. A 64Kbyte on-board video BIOS EPROM is supplied. A DVI-I to DVI-D/HD15 splitter connector cable is supplied as standard.

Operating systems supported include Windows® 2000, Windows® XP, VxWorks®, Linux® and QNX®. Technical datasheet available at
