T1/E1/J1 BITS Element Design Kit

Please check latest availability status for a specific part variant.


The DS26503DK is an easy-to-use evaluation board for the DS26503 T1/E1/J1 BITS element. The DS26503DK is intended to be used as a stand-alone design kit. The board is complete with a DS26503 BITS element, transformers, termination resistors, FPGA-based configuration switches, and network connectors. Dallas' ChipView software gives pointand- 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.
