The AS6500 is a high performance time-to-digital converter (TDC) frontend device. It is a derivative of TDC-GPX2, with CMOS inputs and serial SPI output only. It comes in a QFN40 package.
4-channel TDC with CMOS inputs
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. It calculates calibrated stop measurements, referenced to the applied reference clock.
Combinations of single shot accuracy of 10ps with lowest pulse-to-pulse spacing <5ns and maximum data input burst rate of 70 MSPS per stop input are possible. Total data throughput via SPI is about 1.5 MSPS.
The AS6500-QF development kit is designed as a platform for a quick and easy start of evaluation of the AS6500 time-to-digital converter. The kit offers a graphical user interface for user-friendly configuration and extensive testing of the AS6500.
