The latest version of the company’s time-to-digital converter (TDC) offers improved speed and precision together with low power consumption. The TDC-GPX2 also features standard low-voltage differential signaling (LVDS) and serial peripheral (SPI) interfaces, and a smaller 9 mm x 9 mm QFN64 package. Resolution is up to 10 ps and sampling rate is up to 70 Msamples/s. Other features include an integrated four-channel converter IC offering single-measurement resolution up to 20 psRMS per channel in normal mode. Operating in dual-channel high-resolution mode, it can achieve a maximum resolution of 10psrms with 5ns pulse-to-pulse spacing. Additionally, the TDC dissipates between 60 mW and 450 mW in normal operation, and draws 60 µA in stand-by mode. For more information, go to http://ams.com/Time-to-Digital-Converters/TDC-GPX2
