R. Bassini et al., AN 8-CHANNEL TIME-TO-DIGITAL CONVERTER ON A VME BOARD, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 340(3), 1994, pp. 580-583
An eight-channel time-to-digital converter in a one-slot VME module ha
s been developed. It is based on eight TAC sections and a 1 mus conver
sion time ADC unit with 12 bit resolution. Start and Stop input signal
s can be either NIM or ECL pulses and the Common-Start mode is availab
le. The full-scale time range can be on-board selected between four va
lues from 100 to 800 ns. The integral nonlinearity is less than +/- 0.
04% for all ranges. The Low and High thresholds of any channel and oth
er functions can be remotely controlled.
