TDC-GPX2 4-Channel Time-to-Digital Converter


ams company release new device marked as TDC-GPX2, which is the time-to-digital converter. Highest measurement performance and highest data throughput is achieved with LVDS stop inputs and LVDS serial outputs for each channel. High configuration flexibility and unlimited measurement range cover many applications. 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
