DAC5681Z: IF System

XIN LI

Part Number: DAC5681Z
Other Parts Discussed in Thread: DAC5681

Hello,

I found this diagram in the datasheet of DAC5681Z. What makes me confused is that there is not a DUC in the block diagram. How can we send only I and Q in the DAC and then transmit it ? Am I missing something ?

Thanks in advance,

The DAC5681 is real interface only. The diagram referenced above represents the I/Q in the FPGA or ASIC that will complete the DUC operation before sending the data to the DAC.
