Time-to-digital converter

22 March 2017 Analogue, Mixed Signal, LSI

ams has launched a new version of its time-to-digital converter (TDC) offering improved speed and precision together with low power consumption. The new TDC-GPX2 also features standard low-voltage differential signalling (LVDS) and serial peripheral (SPI) interfaces, and a new, smaller 9 x 9 mm QFN64 package. It enables applications to benefit from increased resolution up to 10 ps and a high sampling rate of up to 70 MSps. The device uses between 60 mW and 450 mW in normal operation, and draws just 60 μA in standby mode. The chip also includes a driver for a quartz reference clock, which enables automatic calibration without the need for an external phase-locked loop or delay-locked loop.
