TIME TO DIGITAL CONVERTERS
AS6501: 2 Channel Time to Digital Converter (TDC)
The AS6501 is a two-channel time-to-digital converter that is ideal for high speed measurement tasks like range finders and medical imaging.
The AS6501 features high speed LVDS interfaces for Start and Stop signals and LVDS measurement outputs. It can be used to measure the time-of-flight of optical signals to a precision of 20ps per channel, or 10ps in dual-channel high-resolution mode with up to 70 Msamples/s and unlimited measurement range.
