Rastergraf's Garnet/PMC is an entry-level, ruggedized conduction-cooled display controller and video-capture PMC (PCI Mezzanine Card). All I/O is via the Pn4 rear-panel connector. For a comparable commercial-grade solution with both front and real panel I/O, please see the Topaz/PMC.

Garnet/PMC features a Silicon Motion SM731 System-on-a-Chip (SOC) graphics accelerator with 16 Mbytes of on-chip SDRAM. This 128-bit 2D/3D graphics engine supports compatible displays at up to 1600 x 1200 x 24 bpp (16.7 million colors).

The card also features the Conexant Bt835 NTSC/PAL/S-Video and analog devices AD9882 high-speed RGB/DVI digitizers. A loopback can connect video output to input for self-testing.

There are a considerable number of choices of inputs and outputs which are configured at time of order: outputs include DVI, dual LVDS, NTSC/PAL composite and S-Video, and primary and secondary analog RGB outputs (with optional Sync-On-Green or Composite Sync). Inputs include DVI, NTSC/PAL Composite and S-Video, high-speed (1280 x 1024) RGB input with optional Sync-on-Green, and NTSC/PAL S-Video and Composite Video. Not all combinations are available at the same time: See the Garnet/PMC datasheet for details.

This PMC card is designed for use under LynxOS (using Curtiss-Wright's SDL) and Linux (using SDL or XFree86) operating environments. It also supports DirectX and OpenGL environments running Windows®.
