The DS3144 design kit is an easy-to-use evaluation board for the DS3144 quad DS3/E3 framer. It is intended to be used as a daughter card with the DK101 motherboard or the DK2000 motherboard. The DS3144DK comes complete with a DS3144 quad framer, DS3154 quad LIU, transformers, termination resistors, network connectors, and motherboard connectors. Interface to the DK101/DK2000 and Dallas' ChipView software give point-and-click access to configuration and status registers from a personal computer. On-board LEDs indicate loss-of-signal, out-of-frame, and interrupt status. An on-board FPGA contains mux logic to connect framer ports to one another or to the DK2000 in a variety of configurations.
