AD9102 - Trouble with DDS mode and reading from SRAM??

Thread Summary

The user is experiencing issues with the AD9102 DAC where only constant value and sawtooth modes work on their proto-layout board, while DDS and SRAM modes do not. The final answer suggests checking the power supply and ensuring the RESET pin is clean, and provides the correct register settings for reading and writing SRAM. The user also noted that the WAV_CONFIG register (0x27) does not retain the correct value when programmed in a sequence, and asks about the impact of noise on the power supply and the behavior of the RAMUPDATE bit.

I have the AD9102 EVboard and I can get all modes to work: constant value, Sawtooth, DDS, and reading from SRAM.  However, on my proto-layout board, I program the Ad9102 SPI directly and I can only get the constant value and Sawtooth mode to work.  The DDS and read from SRAM do not give any output.  I am taking the regval and default sequence from the EVboard software and and programming into AD9102 SPI directly.  So inputting example4 settings gives me the pulsed triangle wave for the sawtooth mode which is working, but the sine wave of example6 is not working.  The registers and SRAM are able to read and write properly. Is this a common problem or am I missing something obvious?  Any help would be appreciated, thanks.
