It is a derivative of TDC-GPX2, with CMOS inputs and serial SPI output only. It comes in a QFN40 package. AS6500 achieves high measurement performance and high data throughput. High configuration flexibility and unlimited measurement range cover many applications, ranging from portable handheld laser range equipment to ambitious time-of-flight measurements of high performance. AS6500 calculates calibrated stop measurements, referenced to the applied reference clock. Combinations of single shot accuracy of 10ps with lowest pulse-to-pulse spacing <10ns and maximum data input burst rate of 70 MSPS per stop input are possible. Total data throughput via SPI is about 1.5 MSPS.
