TDC7201: can process stop and start signals with pulse widths of ~1 ns ?

Hello Guys,

Good day.

Our customer wants to determine if the TDC7201 can process stop and start signals with pulse widths of ~1 ns?

He found the two e2e threads below, but with seemingly contradictory statements. One mentioned that that its 10ns, the other suggests the pulse width can be infinite, hence 1ns is possible.

Details about his application:

He is making measurements (time of flight) on the time delta between 2 signals that are measured by a photodiode. The photodiode voltage response has a sub ns risetime and a pulse width of ~1 ns. The time separation will be above the minimum for the TDC7201 of 250 ps.Thus, he wants to determine if the TDC7201 can process stop and start signals with pulse widths of ~1 ns?

Thanks to confirm!
