What is IMO made up of? Is it some sort of astable multivinbrator kind of circuitry or what exactly is it?
I looked at TRM, no description of its basiuc architecture.
You might want to file a tech case at www.cypress.com to get an answer.
“Create a Case”
Why exactly you want that information? Any specific reasons for it?
These internal oscillators are usually RC oscillators. They are either factory trimmed or calibrated (for the PSoC5 it is the latter one).
This question was out of curiosity. I was just going through the clocks of PSoC and was interested in how IMO works. I just know there is a bandgap refernece on the basis of which it works, but i dont know the exact configuration . So I thought forum will help me in knowing stuffs.
Does any one know what these oscillators are made up of??
You might try the ARM website and ask that question about the M3 Core.
The core documentation for FPGA and SOC silicon integrators should have
As hli said, its a factory trimmed internal RC oscillator. A factory trim for each frequency range is stored in the device.Tolerance usually varies from 1% at the lower (3 MHz) frequencies, up to about 10% at highest setting.
yes as hli said they are RC oscillator with frequency
