USING THE AD9081, AD9082, AD9986, OR AD9988 BOARD VIEW
The board view allows the user to quickly set up the AD9081,
AD9082, AD9986, or AD9988 to a predetermined use case for
evaluation. The board view uses the on-board clocking solution
to manage the clocks to the AD9081, AD9082, AD9986, or
AD9988, as well as the FPGA. For more details on the clock
setup, refer to Figure 20. Figure 21 shows the hardware
connection needed when using the board view with the
AD9082-FMCA-EBZ board as an example.
USE CASES
The use cases in Table 2, Table 3, Table 4, and Table 5 are
supported for JESD204B and JESD204C modes for the AD9081-
FMCA-EBZ, AD9082-FMCA-EBZ, AD9986-FMCB-EBZ, or
AD9988-FMCB-EBZ. Tx means transmit data path, and Rx
means receive data path.
