[DSP-10] 10 mhz reference..

[f5cau]

Most of the time Rb oscillators do not have an electrical control of the
frequency, thus they cant be used with Brooks controler.
This doesnt mean they are good for ever, they do need a calibration from
time to time. After a few months (or years) frequency offset in the 10-9
range is not scarce.
