Introduction
The FDU-160i is a high performance signal distribution amplifier designed for use
with Brandywine high precision time and frequency sources.
The FDU-160i is contained in a compact 1U rack-mount chassis. The system
accepts two of frequency inputs (typically 10MHz). The FDU provides automatic
changeover if one of the on-line source inputs fails, and each input is capable of driving all
sixteen outputs. Manual source select override is available on the front panel, or through
the Ethernet interface.
A variety of status indicators are located on the front panel for instant visual
feedback, together with manual controls for source selection.
A 10/100 base T Ethernet interface provides full control over the functionality of
the system, including reference selection and output amplitude (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 FDU-160i include secure communications systems, satellite
ground stations, digital television broadcasting and any system requiring highly reliable
frequency outputs.

Mounting
The FDU-160i can be installed into a 19” rack mount cabinet either using rack slides or
only using the front panel flanges. For static applications, the short depth and lightweight
of the FDU-160i ensures that the front panel is not stressed when only the front panel is
used for support.
If the FDU-160i is installed on a mobile platform and must survive shock and vibration,
the use of slides is required. Slides are installed using 10-32 UNF-2B hardware.
