I am looking for a Reference Design for the OPT8320. I looked on TI's website and only found the datasheet. Is there Reference Design document available? If so, please provide link or the PDF.
Thanks,
Mo

Hi,
Regarding the questions related to OPT8320, please send them to the email list ti-3dtof@list.ti.com along with a reference to this E2E post.

Hi Alex,
Per your instructions, I sent an email to ti-3dtof@list.ti.com but never receioved a response.
It is veryhard to develop a working hardware with only the datasheet. We know what to with most of the input/outputs but there are certain areas where the datasheet does not provide sufficient information such as :
1) How is the I2C_SLV_ADDR0 used?
2) How are the MOD_CDRIV and VSS_CDRIV used to operate a LED or VCSEL
3) Is the SUB_BIAS -5V or some other value?
4) What conditioning is needed for the power rails (AVDD, AVDD_PLL, MIXH, PVDD, DVDD, ...). I mean what conditioning capacitors should be used?
5) Can we connect the power rails that provide the same voltage to the same supply line, or do we need individual conditioning for each one. For example, could we use the same 3V3 supply source for IOVDD, AVDDH, DVDDH, PVDD?
Wiithout a reference design or direct answer to our questons, we cannot make any more progress, and the project will not progress any further.
Thanks,
Mo
Hi Mo,
My apologies for the delay you saw. I have followed up with the team and I believe you should have received a response now? Please let me know if you are not getting a response still.

Hello Alex,
the response I had from the team was that they dont support this product any longer ...
I know that at one time there was an evaluation kit (Part # : OPT8320-CDK-EVM). Surely, the schematic files for this kit is available. Why can we not get the schematic that will answer a lot of our questions, and we dont have to keep bugging TI with trivial questions?
I would appreciate if you can arrange for the schematics related to the above-mentioned eval. kit to be made available to me.
Thanks and regards,
Mo
Hi Mo,
I heard the team sent over the schematic. Can you confirm?
Best,
Alex
Good to hear. In that case I will mark this post as resolved.
Best,
Alex
