DESCRIPTION
The DS3150DK is a small, self-contained evaluation kit for the DS3150 DS3/E3/STS-1 LIU. A soldered
DS3150 and careful layout of the analog-signal traces ensure maximum signal integrity. Jumpers on the
board allow the user to configure the DS3150 in any mode. LEDs indicate V
CC
present, loss of signal,
transmit driver failure, and PRBS sync. The board provides BNC connectors for the line-side transmit and
receive differential pairs and a header for various system-side signals. On-board oscillators serve as local
timing sources for DS3 and E3 operation. All jumpers, LEDs, and connectors are clearly labeled to make
the board as easy as possible to use.
