New ContributorPin AB19 has a low voltage.
A good board has proper voltage waveform (1.8 Vdc high, and ≤ 0.3 Vdc low).
This is a waveform amplitude of 1.5 volts difference (1.8 Volt rail).
Super ContributorHi,
why are you starting a new thread instead of continuing the previous one? https://community.intel.com/t5/Programmable-Devices/Unexpected-Voltage-output-on-pin-AB19/m-p/1711288
Anyway, now we know at least about used device. Still not clear how the pin is connected in your circuit? How much pull-down current is required by the external circuit to achieve expected 0V level? A schematic would be preferred for explanation. Is it an off-the-shelf development kit or your own design? Which I/O standard is configured for the pin?
Regards
Frank
New Contributor1. why are you starting a new thread ... I was unable to navigate my browser back to the original thread. There was also no eMail link I could use.
2. Still not clear how the pin is connected in your circuit? How much pull-down current is required by the external circuit to achieve expected 0V level? See below.
3. A schematic would be preferred for explanation. I am unable to share the schematic - without and NDA in place. Certainly not on an open forum like this.
4. Is it an off-the-shelf development kit or your own design? Our own design.
5. Which I/O standard is configured for the pin? I will check.
Regular ContributorAny update on questions 2 and 5?
For the schematic, you can share it privately with me via email. Let me know if you wish to send it.

Thank you for the follow up.
Do you happen to know if Boston Scientific has an NDA in place with Intel?
Please send me your eMail address.

Regular ContributorHi Joe,
For your information, I have no access on Intel's NDA and moving forward, we will be referring to Altera NDA.
Let me know if you want to proceed. I will initiate an email to your account.

Regular ContributorJust so you know, I will not have access to this forum until October 14th. I will resume the support after the system is up again.
If you want me to initiate the email, kindly confirm before tomorrow.
