MoCoMRI2, code name Salt uses an external 64 MHz crystal oscillator to provide a clean oscillation at the same frequency. The expected thermal noise level shoud be below -165dBc/Hz and the integrated phase noise between 10Hz and 32MHz be in the 100fs range. The capacitive fine bank tuning should allow us to reach an average tuning step of 0.7 Hz and the coarse bank tuning should allow us to compensate the oscillation frequency by +/- 50ppm. This design is expected to be used in MRI applications.
The codename Salt, comes from the first crystal-controlled oscillator which has been done with a Rochelle salt in 1917, one of the first material discovered to exhibit piezoelectricity.
