TDC-GPX multifunctional High-end Time-to-Digital Converter

General Description

The TDC-GPX is the most powerful member in our TDC family. With its multifunctional architecture, especially designed for applications where high single-shot resolution, best pulse-pair resolution, and high measurement rates are required, the TDC-GPX realizes a huge step forward in time measurement based on TDCs.

With 4 different operation modes, 8-channels with 32-fold multi-hit capability and a resolution down to 10 ps make the TDC-GPX perfectly suited for industrial and scientific applications where the highest performance and precision are demanded.

Features

  • 40 MHz data rate per chip, 200 MHz peak rate
  • 5.5 ns pulse pair resolution
  • LVTTL/LVECL inputs
  • Optional quiet mode for noise reduction in R,G and M-Mode
  • Rising and/or falling edge sensitivity
  • Start-retrigger option
  • 28-bit asynch. parallel data bus (opt. 2 x 16-bit) with Chipselect, Readstrobe, Writestrobe
  • 4-bit address range
  • I/O voltage 3.0 V to 3.6 V
  • Core voltage 2.4 V to 3.6 V
  • Temperature range Tj - 40C to +125C
  • TQFP100, TFBGA120 packages
