The DS21Q55DK is an easy-to-use evaluation board for the DS21Q55 quad T1/E1/J1 transceiver. The DS21Q55DK is intended to be used as a daughter card with the DK101 motherboard or the DK2000 motherboard. The DS21Q55DK comes complete with a DS21Q55 quad SCT, transformers, termination resistors, configuration switches, line-protection circuitry, network connectors, and motherboard connectors. The DK101/DK2000 motherboard and Dallas' ChipView software give point-and-click access to configuration and status registers from a Windows®-based PC. On-board LEDs indicate receive loss-of-signal 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.
Each DS21Q55DK is shipped with a free DK101 motherboard. For complex applications, the DK2000 high-performance demo kit motherboard can be purchased separately.
