DAC38RF84: Interpolation order

Part Number: DAC38RF84
Other Parts Discussed in Thread: DAC38RF85


Can you please confirm me that if we want to use the DAC28RF84, we can not use the order values  of interpolation of 6 and 8? (table 9, page 44, SLASEA3C datasheet)

In this case what is the difference between the DAC38RF85 and DAC38RF84?

Best Regards

  • Hi
    I have notified the DAC38RF84 experts regarding your questions. You should receive a more detailed response soon.

  • F Brest,

    The DAC38RF85 has a differential output and the DAC38RF84 has a wide bandwidth integrated (internal) balun (nominally 700 MHz to 3.8 GHz passband) to

    convert the DAC core differential signal to a single ended signal. The single ended output is expected to drive a 50-Ω load.

    Regarding the 6x and 8x interpolation question, both parts can support this but only when using the required LMFS settings as shown in Table 9.
