GENERAL DESCRIPTION

The DS2155/DS2156 design kits are evaluation boards for the DS2155 and DS2156. The DS2155/DS2156 design kits are intended to be used as daughter cards with either the DK2000 or the DK101 motherboards. The boards are complete with a single-chip transceiver (SCT), transformers, termination resistors, configuration switches, line protection circuitry, network connectors, and an interface to the motherboard.
