Digital Modules

SHF provides a wide range of high performance digital modules suitable for the use in telecommunication systems and test and measurement setups e.g. for SONET OC-768 and SDH STM-256, 100 GbE or Fibre Channel.

Our multiplexers and demultiplexers offer broadband operation up to 120 Gbps with adjustable output amplitude and eye symmetry.

Our digital-to-analog converters are operating at data rates up to 32 or 60 GBaud. Up to six single ended serial data streams are converted into one differential  multi level signal. This makes the SHF DAC an ideal electrical signal source e.g. for PAM or QAM applications.

The limiting amplifier and the D-type flip-flop are ideally suited to clean, re-shape and re-time signals to perfect binary waveforms.
