Advanced FTSU-100D Frequency/ Time Distribution Amplifier

The FTSU-100D is Brandywine’s advanced network enabled distribution amplifier.  The FTSU-100D will accept 1PPS and a reference frequency such as 10MHz from two sources.  A second frequency can be synthesized internally.  8 channels of the reference and synthesized frequency and 1PPS are generated.  Input reference failure results in hitless switchover.  The output frequencies have programmable amplitude and propagation delay compensation.  Available in 1U 19” rack mount this unit has hitless switching and very low phase noise outputs.
