The V660 is a 12-channel time-to-digital converter used to record the time of occurrence of twelve independent electrical pulse inputs, each independently timestamped and buffered in FIFO memory.

The V660 may be used in streaming timestamp or single-shot event modes. Each channel will timestamp events separated by 150 nanoseconds or more.
