... REV. 0 detailed information on the functions of these inputs, as well as the DAC input and output timing, see the AD9709, AD9763, AD9765, and AD9767 data sheets. Operation with a single clock can be achieved by select- ing JP16 or JP9 for the clock source and inserting JP5 in the C position, and removing JP3. JP4 can be used to control IQRESET, but for most evaluations can simply be tied low (Position I) ...

... This is the mea- sured data hold time. REFERENCE OPERATION The AD9709, AD9763, AD9765, AD9767 contain a single 1.2 V reference that is shared by both of the DACs on the chip. This reference drives two control amplifiers that independently control the full-scale output currents in each of the two DACs ...

External Reference Configuration MASTER/SLAVE RESISTOR MODE, GAINCTRL The AD9709, AD9763, AD9765, AD9767 all allow the gain of each channel to be independently set by connecting one R resistor to FSADJ1 and another R SET FSADJ2. To add flexibility and reduce system cost, a single R ...
