I have purchased several (4) of Nick's GPS Disciplining boards for use with an FE-5680A Rubidium, an FE-5650A Rubidium and an FE-405B High performance crystal oscillator. Each of the boards worked perfectly and reliably even with un-powering and re-powering. The outputs of the Rubidiums were tracked via a program and were clearly well disciplined.

English: FE-5680A rubidium frequency standard or "atomic clock", manufactured by FEI Communications. About 5 inches long. It produces a "clock signal" consisting of a digital pulse signal with an extremely accurate frequency. The frequency is stable to 2x10-11 per day or 2x10-9 per year. It requires a warmup period of 5 minutes …

The board was designed to provide a convenient interface to the FE-5680A rubidium frequency reference, including output signal buffering, power I/O and access to the RS-232 pins. For the FEBO-PLL, the board provides a frequency-multiplied output tied to the 10 MHz output. As shown in the schematic, the design is straightforward with FE-5680A ...

3. There are a couple of different variants of these rubidium frequency standards. FE-5650A Option 58 is what you have. It only has the 20-pin connector, no other connector, and some modifications are needed. These devices do work, you can use them fairly easily, but if you want a 10 MHz analog output some modifications are needed.
