FPGA TDC
tapped delay line
t_stamp = ( epoch * 2048 + t_coarse ) * 5ns – Calibr(t_fine)

• required per each TDC channel (~ 48) for each
FPGA design
• may frequently measure calibration tables from
uniform-distributed fine times
• may use known temperature dependency
function
• can be done during data taking with
DABC event builder software • precision ~ 10 ps (without calibration: 200 ps)
