  • 8-channel, 28-bit, 1 nanosecond resolution time-to-digital converter (TDC)
  • Measures events up to 132.8 milliseconds before or after common trigger or 0 to +256.6 milliseconds after trigger
  • Adjustable trigger levels and edge polarity
  • Switchable for use in multi-hit mode
  • Uses advanced CMOS logic for low power consumption
  • Ultrastable, ovenized quartz crystal timebase may be checked and calibrated without removing the module from the crate
  • Compatible with the Le Croy model 4208

The M680 is an 8-channel time-to-digital converter (TDC) used to record the time of occurrence of eight independent electrical pulse inputs. Each channel can time its event "hit" with 1 nanosecond resolution and 28-bit dynamic range. The module has provision for adjustable input logic levels, selectable edge polarity, and provisions for combining channels to perform multi-hit event measurements.

The M680 employs a highly linear time-resolution technique which requires a minimum of adjustment, is easily maintainable, and employs standard bipolar and CMOS logic elements. All optional features are switch-selectable, including the ability to select standard (24-bit) or extended (28-bit) operating modes.
