MODIFYING THE EVALUATION BOARD TO
USE THE ADL5370 ON-BOARD QUADRATURE
MODULATOR
The evaluation board contains an Analog Devices, Inc.,
ADL5370 quadrature modulator. The AD9714/AD9715/
AD9716/AD9717 and the ADL5370 provide an easy-to-
interface DAC/modulator combination that can be easily
characterized on the evaluation board. Solderable jumpers
can be configured to evaluate the single-ended or differential
outputs of the AD9714/AD9715/AD9716/AD9717. This setup
is the default configuration from the factory and consists of
the following population of the components:
 JP55, JP56, JP76, JP82—unsoldered
 R13, R14, R52, R53—unpopulated
 R50, R57, T1, T2—populated
To evaluate the ADL5370 on this board, the population of these
same components should be reversed so that they are in the
following positions:
 JP55, JP56, JP76, JP82—soldered
 R13, R14, R52, R53—populated
 R50, R57, T1, T2—unpopulated
The AUXDAC outputs can be connected to Test Point TP44 and
Test Point TP45 if LO feedthrough compensation is necessary.
