DS91C176EVK User Manual
Board Description
Figure 2 shows the adapter board drawing with the silkscreen annotations. The 2.5 by 3.0 inch,
four-layer PCB is designed to bring RJ45 connector signal pins to SMA connectors. The SMA
connector annotations correspond to the RJ45 connector pin numbers. There are only 2 SMA
pairs installed (1&2 and 7&8) on the board. The end user may install additional SMA connectors.
One of the RJ45 connector signal pin pairs (3 and 6) are connected to DS91C176 (U1) M-LVDS
I/O pins. There is a provision to disconnect the DS91C176 M-LVDS pins and connect the SMA
connectors (3 and 6).
The JP2 and JP3 connectors connect to the DS91C176 LVCMOS I/O and control pins.
