Hello everyone,
I am working on a project where I need to sample a sine wave then fit it to get it's magnitude, I need to cover the range of 1 Hz to 1 MHz.
I have already accomplished the range from 1 Hz to 100 kHz with the internal ADC of the teensy 3.6 and I connected it to python to fit the signal, but I am struggling with the high frequency due to the fact that I need a very fast sampling ADC (5 to 10 MSPS). I thought I would be able to use LTC2315-12 which uses spi to interface with the controller and can accomplish 5MSPS, but I need the spi clk to be 89.7 MHz exactly which seems to be above the teensy maximum. The other way was to use an ADC with a parallel interface and generate the clk from the teensy to controll it but I am not sure if this would be efficient since I would have to overclock the controller and keep it running to read the ports on the maximum speed.
I was wondering if anyone worked in this frequency range and has any suggestion and also if I wanted to use the parallel interface ADCs is there any timer/interrupt in the teensy 3.6 that can be set up to 5 MHz?!
Thanks in advance.
