  • Product Details

    The DS3254DK is an easy-to-use evaluation kit for the DS3254 quad DS3/E3/STS-1 LIU. A surfacemounted DS3254 and careful layout of the analog signal traces provide maximum signal integrity to demonstrate the transmit and receive capabilities of the DS3254. On-board Dallas 8051-compatible microcontroller and included software give point-andclick access to configuration and status registers from a personal computer. LEDs on the board indicate interrupt, loss-of-signal, transmit driver monitor, and PRBS sync status for all four ports. The board provides BNC connectors for the line-side transmit and receive differential pairs and a 50-pin connector for framer interface signals. All LEDs and connectors are clearly labeled with silk screening to identify associated signals.
