Description 

The FX364 is a instrumentation Analog Front End (AFE) integrated circuit (IC) is designed to enable 100ohm single-ended time-domain impedance and transmission measurements via time-domain reflectometry.  By monolithically integrating a single-ended 50Ω 10ps rise-time step generator with an ultra-fast 30GHz Sample and Hold Amplifier, the FX364 enables a class of time-domain reflectance, time-domain transmission, S11, S21, NEXT and FEXT characterization. 

Applications 

  • Board, connector, cable interconnect analysis
  • Manufacture/end-user cable assembly testing
  • Allows impedance characterization, to 5m
  • IC/system Automated Test Equipment (ATE)
  • Handheld test & measurement
  • Communications Systems/Backplane test
