Break-Out Boards
Dual 38-Pin Break-Out Board
This board is intended for differential testing, however it can also be used for single-ended
signals. For single-ended signals, the data is transmitted on the positive lines.
Figure 3-2
shows
this break-out board along with the pin-out diagram for the connectors. Notice that the parallel I
and Q signals are separated by connectors; J1 provides the Q signals and J2 provides the I
signals. The serial signals are also provided on the J2 connector.
For the N5102A module to receive a clock through the Device Interface connector by way of this
break-out board, a jumper wire is required at the 2 to C1 contacts for a negative clock and at the
1 to C2 contacts for a positive clock. This is shown in
Figure
3-2.
The VCCIO (selected high logic level voltage) is obtained at J4, while the + 5 volt unfiltered DC
supply is acquired at J3.
