DS3184DK
Quad ATM/Packet PHYs for DS3/E3/STS-1 with Built-In LIU Demo Kit
GENERAL DESCRIPTION The DS3184DK is an easy-to-use demo kit for the
DS3184. A surface-mounted DS3184 and careful
layout of the analog signal traces provide maximum
signal integrity to demonstrate the transmit and
receive capabilities of the DS3184. On-board Dallas
8051-compatible microcontroller and included
software give point-and-click access to configuration
and status registers from a personal computer.
General-purpose LEDs on the board can easily be
configured to indicate various alarm conditions for all
four ports. The board provides eight BNC connectors
for the line-side transmit and receive differential
pairs, two 140-pin connectors for system interface
signals, and two FPGAs to support overhead
functions. All LEDs and connectors are clearly
labeled with silkscreening to identify associated
signals.

DS3184 Demo Kit
BOARD FLOOR PLAN Figure 1 shows the floor plan of the DS3184DK. The DS3184 is near the center of the board. The analog circuitry is
on the right side of the board, which includes transformers and BNC connectors. There is an optional external LIU
(DS3154) that can be used in certain configurations. Located one above and one below of the DS3184 are two
FPGAs that, along with headers, provide access to the overhead signals. The microprocessor is on the left top of
the board, clock distribution is in the left center, and system interface is at the left bottom. General-purpose LEDs,
which are driven by configurable outputs, are located at the top of the board. In the upper-left corner are banana
jacks for ground, 5V (regulated to provide board VDD), and a separate DS3184 VDD (useful for DS3184 IDD
measurements). There are connectors provided for the serial interface to the microprocessor and the JTAG chain.
The board also contains DS3, E3, and STS1 oscillators and the necessary jumpers to configure both the DS3184
and the DS3154 clocking.
