MODIFYING THE EVALUATION BOARD TO USE
THE AD8349 ON-BOARD QUADRATURE
MODULATOR
The evaluation board contains an Analog Devices
AD8349
quadrature modulator. The AD977x and AD8349 provide an
easy-to-interface DAC/modulator combination that can be
easily evaluated on the evaluation board. To route the DAC
output signal to the quadrature modulator, the following
jumper settings must be made:
Unsoldered: JP14, JP15, JP16, JP17
Soldered: JP2, JP3, JP4, JP8
The DAC output area of the evaluation board is shown in
Figure 103. The jumpers that need to be changed to use the
AD8349 are circled. Also circled are the 5 V and GND
connections for the AD8349.
