AS6500: Time to Digital Converter (TDC)
The AS6500 is a high performance time-to-digital converter (TDC) frontend device. It is a derivative of the TDC-GPX2, with CMOS inputs and serial SPI output only. It comes in a QFN40 package.
High data throughput and measurement performance are attained by the AS6500 TDC. Numerous applications are covered by the high configuration flexibility and infinite measurement range, from high-performance time-of-flight measurements to small handheld laser rangefinders. It computes stop measures that are calibrated and compared to the applied reference clock.
It is achievable to combine the lowest pulse-to-pulse spacing of <5 ns with a single shot precision of 10 ps and a maximum data input burst rate of 70 MSPS per stop input. SPI allows for a total data rate of roughly 1.5 MSPS.
