The DS3112RD is a reference design for the DS3112 DS3/E3 framer/mux and the DS3150 DS3/E3 LIU. Both devices are surface-mounted to minimize board size and to provide signal integrity. Interface to the DK101/DK2000 and included software give point-and-click access to configuration and status registers from a personal computer. LEDs on the board indicate loss-of-signal, transmit driver monitor, and PRBS sync status of the LIU. The board provides BNC connectors for an external clock, the line-side transmit and receive differential pairs, and a connector for data path interface. A PLD provides registered access to the LIU control pins along with control of clock and data paths.
