We noticed in the datasheet that the power and currents quotes all come with the footnote, DDC off. Are the numbers with the DDC on available or is there a % we should add to the given numbers to help us with our analysis?
The power with DDC on is available, though there are many different possible configurations. I think the quickest way would be for you to tell me what configuration you are interested in (sample rate, decimation ratio, JESD configuration), and I'll try to take a quick measurement.
Thanks Doug! We are running at 5Gsps, decimate by 2, JESD 8 lanes at 12.5G, M=2, N/N'=16.
I appreciate it!
Under the conditions you specified (5Gsps, decimate-by-2, 8 lanes, M = 2, N' = N = 16) the total power on a typical AD9213-10G part on my bench was 3.312W. The supply voltages were at 1.0V and 2.0V. This is in the same ballpark as the number from Figure 46 in the AD9213 Rev0 datasheet, though the ADC is in a different configuration from the one you specified.
The major power contributors in today's test were as follows:AVDD (1.0V): 1.63WJVDD (1.0V): 433mWDVDD (1.0V): 455mW
To have a signal present at the input I applied a 2.6GHz 6dBm tone to the analog input of the board. I had the NCO frequency set to 0Hz so a tone at this frequency would be converted by the core but the decimation filters would attenuate it so that you would not see much of it in the output codes.
FYI the presence of an input signal makes very little difference in AD9213 power but I applied the test tone anyway.
I hope you have a nice weekend.
Thanks a lot! I really appreciate it.
You are very welcome.
