Hello,
I plan to use a MP2 on a SOM module (probably something like the KaRo QFN-like QSMP2 module).
This MP will run a linux on the A35 core and real-time software on the M33, + USB2, ETH 100 Mbps.
I need 11 ADC channels to convert analog signals at 500kSPS. There is enough ADC input to do that at the required sample rate but what about noise ?
The datasheet claims ~9.3bits of ENOB, this the enough BUT I suppose that obviously, this is in the best case.
Activating LPDDR4 + USB2 + ETH will generate a lot of board noise and will probably degrade the ADC ENOB. But how much ?
Does anyone experienced some noise measurement on MP1/MP2 device with DDR and hi-speed IF activated ?
Thanks for the feedback !
