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.

The FTSU-100D is a high performance signal distribution amplifier designed for use with Brandywine high precision time and frequency sources. The FTSU-100D is contained in a compact IU rack-mount chassis. The FTSU accepts two sets of inputs, comprising the reference frequency (typically10MHz) , 1PPS, and status from the source. The FTSU provides automatic changeover should one of the on-line source inputs fail. Manual source

select override is available on the front  panel, or from the Ethernet interface.

A variety of status indicators are located on the front panel for visual feedback, together with manual controls for source selection The reference frequency outputs are generated from a low phase noise ovenized quartz oscillator (OCXO) that is phase-locked to the reference frequency input. In the event of reference input
failure the phase-locked oscillator will continue to provide referenced frequency outputs with a stability of 3X10
-9 over temperature. Changeover between references is smooth with no glitch on the output.

A 10/100 baseT Ethernet interface provides full control over the functionality of the system, including reference reflection, output amplitude (on a per channel basis), 1PPS propagation delay (on a per channel basis).  User control of the unit is via a built-in Web Browser with user-friendly graphical interface, or via SNMP for system applications.


Applications for the FTSU 100D include secure communications systems, satellite ground stations, digital television broadcasting and any system requiring highly reliable frequency, and pulse rate outputs.
