The TDC2 is a timestamping/timetagging device for processing electrical pulses in four independent inputs. It can accept standardized signal standards including (NIM and TTL) and requires an external +12V power input . The internal clock source can be disciplined by an external 10 MHz timing reference for precise absolute timing.
The device registers the absolute time of the leading edge every signal event (pulse) at any of the input lines with a resolution of 8ps (30ps jitter) for pulses separated by more than 50ns.
The TDC2 requires a driver which is available for Linux OS for now.
