EDT Combo 3 E3/T3, ECL, or LVDS/RS422 interface

EDT Combo 3 E3/T3, ECL, or LVDS/RS422 interface


  • Mezzanine board — pairs with an EDT main board (PCI or PCIe), which adds DMA, programmable FPGA resources, and memory
  • I/O: Electronically selected, not jumpered
    - Standard = E1/T1 (sixteen I/O interfaces) and E3/T3 (four I/O interfaces)
    - Optional = ECL / LVDS / RS422 (eight synchronous serial pairs, each with one clock signal and one data signal, for a total of sixteen signals in groups of four)

The Combo 3 is a mezzanine board that pairs with the EDT PCIe8 LX Main Board to support multiple standards. It supports E3/T3, ECL, LVDS, or RS422 signals and processes communications serial data for complex, user-defined applications.

For details on system requirements and EDT-provided software driver packages, see the specifications for your EDT PCIe8 LX Main Board.

Note: The Combo 3 uses EOL parts of which we have limited supplies on-hand; therefore this product, while still available to ship in limited quantities, is nearing its end-of-life. Support for E1/T1 has been retired in the Combo3 board due to changes in parts availability. Support for the Combo 3 on PCI SS main boards is no longer available.

The E1 line interface unit (LIU) on the original Combo 3 mezzanine board is being retired because of parts discontinuance by suppliers. We wanted to let you know about this change and how we are supporting our customers who use this board.

First, we are now offering a new, lower-cost version of the board, identical to the original except without E1 support. We encourage you to consider switching to this “no E1” version, at a price lower than that of the original board.

Second, we still have parts available to fulfill reduced order levels of the original Combo 3 with E1 support. However, if you foresee an increased need for this board, let us know and we’ll research options to support that need for you.
