TDC-GPX2
4-Channel Time-to-Digital Converter
General Description The GPX2 is a high performance time-to-digital converter (TDC)
frontend device.
Highest measurement performance and highest data
throughput is achieved with LVDS stop inputs and LVDS serial
outputs for each channel. Current saving operation is also
possible with CMOS inputs and SPI readout.
High configuration flexibility and unlimited measurement
range cover many applications. They range from portable
handheld laser range equipment to ambitious time-of-flight
measurements of highest performance, as e.g. done in medical
imaging applications.
GPX2 operates without any locked loop technologies. GPX2
calculates all stop measurements inside, proportional to the
applied reference clock. Combinations of best single shot
accuracy of 10ps with lowest pulse-to-pulse spacing SV@ Figure 19:
