AMC7823: What is the internal clock frequency of the AMC7823

Hi Paul,

It will take some time me to get the oscillator frequency value. The oscillator is not able to be turned off.

What do you require the oscillator be turned off for? It controls the ADC and SPI timing.

Thanks,
Erin

Hi Erin - I'm still interested in knowing the internal clock frequency for the AMC7823. I'm hunting down some spurs and that information would be really useful.
To answer your question: I wanted to turn off the internal clock after the DACs were set, based on ADC measurements. I'm making a low noise current source and this clock is the only clock on the board. If I could disable it, that would have been great - I understand that this is not possible. I'm seeing some spurs now and wanted to distinguish which are from the AMC7823 clock and which are external signals. Can you find the clock frequency for me?  Thanks much!

Hi Paul,

I'll see if I can find out the frequency, I'll update you in a few days.

Thanks,
Erin
