very easy. If you have a main clock 36Mhz and the thermometer code frequency is 1Mhz, while thermometer code bit width is less than 36bit, than you can count the number of 1 at 36Mhz frequency, and the corresponding binary code can be get in one thermometer code period.
I think your example is not suitable for me.
For my application, the main clock is around 60MHz and thermometer code is parallel 63-bit input and 60MHz input rate.
Do you know how to design them?
Thank you.
