I am using the adrv9002 and have something running but i do not think i have a good configuration for DACs.
I used TES to generate the code to give me 20Msps.
I use the API for the spi portion of configuration.
I am manually configuring the FPGA9001 portion.
I have a question on the clock registers for the DAC on the following:
0x004c REG_RATECNTRL DAC is read write
0x0054 REG_STATUS1 read only
0x0058 REG_STATUS2 read only
I am using the info from here https://wiki.analog.com/resources/eval/user-guides/adrv9002/axi_adrv9002#dac_common_axi_ad
What am i supposed to read for registers 0x0054 REG_STATUS1 ?
I am getting 0x0.
For the clock rato 0x0058 REG_STATUS2 i am getting 4.
What would i set 0x004c REG_RATECNTRL DAC to?
The description says "The effective dac rate (the maximum possible rate is dependent on the interface clock). The samples are generated at 1/RATE of the interface clock. "
I am running from a Zedboard with so i the clock is 100MHz.
Would i set the RateCntl to 5 so i get 100 / 5 = 20 Msps?
My TES config is for 20 Msps using DDR CMOS 4 lanes.
Thanks
