The GFT2505 is a common-start time-to-digital converter. The timestamps of leading or trailing edges of digital pulses are recorded.
The xTDC4 produces a stream of output packets, each containing data from a single start event, i.e. the relative timestamps of all stop pulses that occur within the user deﬁned range.
The GFT2505 is a high precision common start time to Digital Converter (TDC). The times stamps of leading or trailing edges of digital pulses are recorded with a single shot resolution of 13 ps.
The inputs are AC coupled and have an impedance of 50Ω. The digital threshold can be adjusted in order to comply with a manifold of single ended signals enabling the acquisition of positive or negative pulses.
The TDC is supplied with a standard device driver that can be used to command and control the device and acquire the data.
