Other Parts Discussed in Thread: AMC1204, CONTROLSUITE
I'm trying to work on using a Sigma Delta Filter Module to measure an isolated voltage. From a high level, I would like to read a voltage at 500 Hz.
My hardware is a AMC1204 and the TMS320F28377S Launchpad.
The first thing I would like to figure out is how to properly hook these up. I would like to connect to GPIO58 and GPIO59 for the second SDFM (channel 2) on the processor. Do these connect to pins 6 and 7 on the AMC1204? I guess I am wondering how to generate the 20 MHz "Modulator Clock Input" on the AMC1204, and the "Sigma-Delta 2 channel 2 clock input" on the F28377S.
I read in the TRM that PWM12 can be used to synchronize things, but what is being used to generate the Sigma Delta Clock for the chip?
