TDC-GPX High-End Time-to-Digital Converter

The TDC-GPX2 is the most powerful member in our TDC family. Highest measurement performance and highest data throughput is achieved with LVDS stop inputs and LVDS serial output for each channel. Current saving operation is also possible with CMOS inputs and SPI readout. High configuration flexibility covers many applications. Applications range from gaming, portable handheld laser range equipment to ambitious time-of-flight of highest performance, such as in medical imaging applications. GPX2 operates without any locked loop technologies. All stop event measurement times are calibrated inside the GPX2 proportional to the applied reference clock. Combinations of best single-shot accuracy of 10ps with lowest pulse-to-pulse spacing 5ns and maximum data throughput rate 70 MBPS per stop input are possible.

Product name

TDC-GP21 Ultrasonic Flow Converter

TDC-GP21 is a 2-channel TDC with additional analog elements like extended fire-pulse generator, zero-cross detection and analog switches for simplifying the use in ultrasonic flow meter applications. An optimized power managements of the various units brings down the operating current to a few µA at 2Hz measuring rate.
