T1/E1/J1/64KCC Bits Element Design Kit

Please check latest availability status for a specific part variant.


The DS26502DK is an easy-to-use evaluation board for the DS26502 T1/E1/J1/64KCC BITS element. The DS26502DK is intended to be used as a stand-alone design kit. The board is complete with a DS26502 BITS element, transformers, termination resistors, FPGA-based configuration switches, and network connectors. Dallas' ChipView software gives 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 as well as multiple clock and signal routing configurations.
