	NEW: Multichannel FLEXI-TDC optimized for multihit-measurements

A 48-fold multichannel Flexi-TDC optimized for multihit-measurements has been developed on basis of our fast Flexi-TDC-System. 6 GPX TDCs with 8 input channels each and with one of them per TDC useable as a free programmable time reference input channel offer a multihit aquisition of e.g. up to 84 pulses/12.5ns. Data transfer with a transfer rate of up to 3Mcounts/s in the raw data mode is done via USB2.0. The measuring rate can be increased by a flexible programmable data pre-processing within the FPGA (e.g. histogram memory). Beside the standard input level NIM also customer specific adaptions are possible (e.g. LVTTL, PECL, ECL).

Technical Data:
- 6 integrated ACAM GPX TDC chips
- Up to 48 input channels (8 per TDC)
- One input channel per TDC can be used as a
   free programmable time reference input
   channel
- Double pulse resolution of min. 6ns for events
   within one channel and 0ns between different
   channels (e.g. up to 84 pulses/12.5ns)
- Each channel consists of a 32-fold buffer for
   multihit aquisition
- 3 Mcounts/s transfer rate (in raw data mode,
   devided up to all used entrance channels) via
   USB2.0
- Higher measuring rates are possible, depending
   on data preprocessing within the FPGA
- Flexible data preprocessing programmable (e.g.
   internal histogram memory)
- Histogram resolution typ. 90ps
- Best possible resolution within a single histogram
   180ps
- Internal TDC readout frequency up to 40 MHz
- Input level NIM, other levels are available on
   demand (e.g. LVTTL, PECL, ECL)


	Also available now: 4-fold to 6-fold multichannel Flexi-TDCs with an increased histogram resolution of up to 30ps. These devices contain 1 - 3 GPX chips with an internal readout frequency of up to 20 MHz each and 2 input channels per TDC.


	The NEW USB2.0-TDC: Our improved Time-to-Digital Converters for all delay line detectors


	Technical Data: - Single ACAM GPX TDC chip - 8 input channels - up to 41 �m pixel size - up to 81 ps digital time bin resolution - up to 3 MHz countrate - Internal TDC readout frequency up to 40 MHz - Input level LVTTL
