bimbla, any more specific request?

For reseacrh, for integration to project/product, specifications, purchasing, packages......

For research and for integration into a project/ product.
Besides variable freq, what are its other advantages over regular Xtal and Xtal block?

This oscillator can be phase locked to another one. The phase noise will be much lower than any other resonator type oscillator. I have seen a precision frequency reference which used a very stable oscillator which as a by-product had poor phase noise. This noise was removed by using another VCXO in a PLL. The second oscillator had good phase noise but poor stability if used in the ordinary XO mode.

It is common to use a 1 MHz crystal on the 5th overtone to make a 5 MHz source. This gives it 25x bette stability than the same type operating at 5 MHz on the fundamental of the crystal.
