Complete Interface module for the FE-5680A Rubidium Source.  Unit is a small double sided, solder masked, silk screened unit that incorporates the following featurs 1.  An on-board DB9 connector that mates with the FE module 2. On board 5 volt regulator required to supply the 5 vdc requirement for the FE module 3. On board 3.3 vdc regulator to supply the buffer logic 4. On Board logic supplies the level converter for the 0.5 volt rms signal  to CMOS logic level (3.3) 5. On board logic provides 4 each buffered 10 MH signals 6. On board logic provides a current limited LED drive to indicate a Rubidium lock condition 7. The serial rs 232 lines to and from the FE module are brought out to a header for easy connection (FE unit you have may or may not have that option included) 8. An on board PLL system that allows the 10 MHz rubidium signal to be digitally multiplied  buy 2X,  2.5X,  3X,  3.3333333333X,  4X,   or 5X  can be selected via on board jumpers  The overall jitter specification for this output is <45 picoseconds not  including jitter originating in the Rubidium Unit.  This feature is quite useful when driving DDS chips at higher frequencies for DDS VFOs   For example:  the 2.5X option used in conjunction  with an Analog Devices AD9851 chip's 6X multiplier would produce a Source Clock of 150 MHz locked to the Rubidium source. 9.  Fully documented with hook up data, schematic and support documents. User must supply their own power wart that delivers between 15 and 18 vdc at around 2 amperes.  Surplus Dell and other Laptop power warts are quite suitable for this purpose. Item ships fully assembled and tested  Thank you for the read
