DDS: phase offset from RAM (PHASE_MEM_EN3) available only for DAC3 ?

Category: Datasheet/Specs
Product Number: AD9106

Is the phase offset from RAM feature (PHASE_MEM_EN3) available only for DAC3, i.e. only on 1 out of 4 channels?

If so, are there similar ICs that could be recommended (I will keep looking meanwhile). Thank you.

    Yes, unfortunately, the PHASE_MEM_EN is for a single channel (DAC3) only. The PHASE_MEM_EN3 is used to provide an offset to the DDS waveform based on the contents of the SRAM registers. It may be more convenient to use the DDS Phase Offset Registers, DDSx_PW registers (Registers 0x40 to 0x43) to apply a phase offset to a prestored DDS waveform. The DDS can apply to all 4 channels.
