Description
The Combo 2 is a mezzanine board which pairs with an EDT main board (PCIe8 LX, PCI GS, or PCI SS) to provide multiple telecommunication and LVDS / RS422 interfaces. The board pair supports the processing of large amounts of telecom serial or LVDS / RS422 data for complex, user-defined applications. The high-speed 16-channel DMA controller allows flexible access to host memory. The main board supplies DMA, memory, and programmable FPGA resources (see ordering options below); EDT provides FPGA configuration files.
