How much should be the input rise time of the start/stop pulse to a TDC? What determines it?

Hi,

I don't understand your question .... because we don't know which IC you use nor do we know your application requirements.

General answer:
If I wanted to know this, I'd read it's datasheet.

At least fast enough to allow clear edge detection, preferably fast enough not to introduce additional timing uncertainty.
