EDT Combo 2 E1/T1, E3/T3, LVDS or RS422 interface

Features

Sixteen E1/T1 line interfaces
Four E3/T3 line interfaces
Sixteen LVDS (TIA644 standard) or RS422 differential inputs/output (input or output in groups of four)
Large Xilinx FPGA provided by EDT PCIe8 LX mainboard
Two large synchronous static memory banks or one memory bank up to 1 GB (also provided by mainboard – see details below)
LVDS External clock that can be used to synchronize the output data
Sixteen independent DMA channels to host memory
Fast transfers using a 66 MHz 32-bit PCI

Applications

Telecommunications network monitoring
Telecommunications switching

The Combo 2 is a mezzanine board which pairs with an EDT PCIe8 LX main board 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.
