We are trying to get the AD9152 up and running on our own custom boards and are running in to problems trying to configure it in a DC test mode. We are using a 245.76MHz REFCLK. I am setting the registers as in the spreadsheet I have attached. I use step 1 and 2 and then configure DC test mode to a large amplitude with an fs/8 modulation. Our DAC PLL is locking so I think I have that part correct. TXEN is set high. I have disabled DAC Protect mode in startup by setting register 0x12C to 0x00 as well.
Despite all this, I have been unable to get any output out of our DAC at all. Does anyone have any idea what I'm doing wrong?
Thanks so much!!
