The AS6501 is a high performance 2-channel time-to-digital converter (TDC) frontend device based and derived from TDCGPX2. Highest measurement performance and highest data throughput is achieved with LVDS stop inputs and LVDS serial outputs for each channel.
2-Channel TDC with LVDSA Inputs/Outputs
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. AS6501 operates without any locked loop technologies.
AS6501 calculates all stop measurements inside, proportional to the applied reference clock. Combinations of best single shot accuracy of 10 ps with lowest pulse-to-pulse spacing <5 ns and maximum data throughput rate of 70 MSPS per stop input are possible.
The AS6501 development kit allows customers a quick and intuitive approach to using the AS6501 2-channel time-to-digital converter.
