Please could you provide the following information for the SM320F2808PZMEP internal oscillator circuitry:-

Value of the (assumed internal) feedback resistor Rf across pins X1 and X2
Input and output capacitance of the (internal oscillator) inverter gate between pins X1 and X2
gm (transconductance) of the inverter gate, and, if possible, the output resistance of the inverter gate
propagation delay of the inverter gate.

Hi,

The engineer supporting this device is out of the office until Monday April 2nd. In his absence, I will attempt to find someone knowledgeable with the design to answer your questions.

Thanks
Christian

Thank you. I'm hoping the engineer supporting this device is back in the office - is it possible now to provide the data?

Dave, Robert,
We have investigated this, and determined that we do not have this level of detail available on the oscillator cell.
I was able to locate what I believe to be the correct macro library datasheet for the oscillator, and this information is not available.

If this answers your question, please click "Verify it as the answer"
Regards,
Wade

Thank you, Wade, for investigating. Dave, although the requested data couldn't be located, I've liaised with Wade over a number of years, and accept that the data isn't available. As the original poster, please click "Verify it as the answer" on my behalf if available to you. ("Suggest as Answer" only is available to me - I'll click it anyway).
