For those cases we recommend the use of USB2.0. Note The use of USB2.0 is always possible, but there might be limitations in the maximum count rates for certain detector types and/or detector operation modes. Time-to-Digital-Converter Octa Channel TDC Manual | Surface Concept GmbH... -
Page 11: Tdc Layout
4 TDC Layout 4.1 Schematic Description of the Octa Channel TDC The Octa Channel TDC series combines the excellent performance of the GPX TDC chip with a high speed USB (R442) or an Ethernet interface (R443, R451, R461). A field programmable gate array (FPGA) enables a comfortable setup and a variable data stream handling from the TDC via USB and Ethernet. - Page 12 Communication to and from the PC is achieved via a USB or Ethernet interface. Data streaming via the interface is provided without losses using a large memory buffer within the device. Time-to-Digital-Converter Octa Channel TDC Manual | Surface Concept GmbH...

Page 16: Start Frequency Divider
4.2.5 Start Frequency Divider The maximum start frequency for the Octa Channel TDC is restricted to 9MHz. To cope with larger start frequencies the Octa Channel TDC is equipped with an internal start frequency divider for external start frequencies of up to 150MHz (this mode only works when using the external start input). Herewith the frequency divider can operate with different dividing factors, which can be set within the software, to always guarantee a start frequency of below 9MHz. -
Page 17: Master Reset Input
FIFOs of the TDC chip are cleared (all old TDC data are erased). A LVTTL (low voltage TTL) signal on 50Ohms has to be applied to the “MASTER RESET IN“ (BNC socket) of the TDC. Time-to-Digital-Converter Octa Channel TDC Manual | Surface Concept GmbH... -
Page 18: State Signal Input
The shutter signal has to be applied as a LVTTL (low voltage TTL) signal on 50Ohms to the “SHUTTER IN“ (BNC socket) of the TDC. Time-to-Digital-Converter Octa Channel TDC Manual | Surface Concept GmbH... -
