Using the AD9102 with 1.8V power supply
By default the AD9102-EBZ evaluation board uses 3.3V digital and clock power supplies. On-chip CLDO, DLDO1
and DLDO2 supplies are used. P15, P13, and P11 are not installed.
It is possible to operate the AD9102 with 1.8V power supply only. To achieve this, a few changes are needed:
1.
Set the voltage of the DVDD and CVDD regulators on the AD9102 evaluation board to 1.8V on the
BOARD CONFIG tab of the AD9102 evaluation software – see Figure 11. This will assure that SPI
communication and the AD9102 clock power supply pins are powered with 1.8V
2.
Install jumpers in P15, P13 and P11. These jumpers connect 1.8V regulators on the evaluation board with
DLDO1, DLDO2 and CLKLDO pins of the AD9102.
