Part Number: DAC3484 Other Parts Discussed in Thread: LMK04826 , Tool/software: Dears, My customer is using DAC3484 in a RF station project, and find the measured IMD3 may be 60dbc, so some PCBAs could not pass the test. the customer used DAC3484 previously, it worked ok, the issue happened when the new project is required to support expanded frequency scope, and the corresponding DAC output frequency was also expanded accordingly. The customer tested the PCBA with signal source directly supplies the signal to the DAC3484, and the DAC directly outputs the signal differential line to connect the balun for direct measurement. would you please help to have a look of the issue? if any further information, data you may need, please let us know. In addition, the customer also wonder if DAC3484 have a register to support the debugging function of directly sending dual-tone signals? thanks a lot!
