BOARD FLOORPLAN
Figure 1 shows the floor plan of the DS26519DK. The DS26519 is near the center of the board. The network
connections are provided on the right side of the board, which includes transformers and stacked RJ48 connectors.
Toward the center of the board are two FPGAs that provide muxes for control of system-side connections via
memory-mapped registers. Above and below the DS26519 are headers that provide access to all system-side
signals. The GPIO circuits next to the system connectors provide an interface to the GPIO pins via a header and an
LED for each GPIO. The power-supply connections, microprocessor, and JTAG connection are all in the top left
quadrant of the board. The power-supply section has three banana jacks for 3.3V, ground, and programming (used
at the factory). The bottom left quadrant of the board houses a serial port connector for interface to a computer and
clock distribution circuitry.
