TDC: MODIFICATIONS & OPEN QUESTIONS l TDC: MODIFICATIONS & OPEN QUESTIONS Pulse width larger than 255 ns will not be discarded?: 1.- Should we change the data format?More bits for width? 2.- Should we split it in differents hits?? FIFO T_STAMP (ns) WIDTH (ns) 30 10 60 254 16 626 15 10 516 15 30 20 50 Pulse width = “11111111” reserved for new time slice

TDC: MODIFICATIONS & OPEN QUESTIONS l TDC: MODIFICATIONS & OPEN QUESTIONS Pulse width larger than 255 ns will not be discarded What about if change of time slice is during the width?? 1. Should we stored in the previous time slice?? FIFO CH 1 T_STAMP WIDTH 30 10 60 254 16 Special_mark 255 366 15 New time slice 10 516 15 30 20 50 200 316 2. Should we split it in differents time slices ?? 3. Other options…
