FX333 Sample & Hold

The FX333 is a high-performance, low noise, wide-band, fast, fully differential, dual rank, track & hold, capable of tracking DC to 16GHz input signals and sampling these signals at rates from 50MS/s to over 1GS/s. It incorporates two cascaded fully-differential track-and-holds that are edge-triggered, respectively, by the applied clock and the internal inversion of the clock.
