Product Details

The DS26401DK is an easy-to-use evaluation board for the DS26401 octal T1/E1/J1 framer. It is intended to be used as a daughter card with the DK101 motherboard or the DK2000 motherboard. The DS26401DK comes complete with a DS26401 octal framer, two DS21448 quad LIUs, transformers, termination resistors, network connectors, and motherboard connectors. The DK101/DK2000 motherboard and the Dallas' ChipView software give point-and-click access to configurations and status registers from a Windows® -based PC. On-board LEDs indicate loss-of-signal, loss-of-frame, and interrupt status.

Each DS26401DK is shipped with a free DK101 motherboard. For complex applications, the DK2000 high-performance demo kit motherboard can be purchased separately.
