If you have a legitimate application for the part, and some volume
associated with the application, and you convince their sales person of
that, then the data sheets are made available.

It's not unusual for one to be able to get small quantities of a 
pre-release product if you have a relationship with the 
manufacturer/sales engineers. Typically it's bound up with an NDA, and 
the datasheet is NDA, and you basically have an agreement that if it 
turns out poorly so they can redesign/retool/fix it, you tell the mfr 
about it, and don't go broadcasting to the world that this new part is junk.


In otherwords, not everything is available through distribution and 
mail-order.


This is one of the arguments I make as to why attending in-person 
conferences is a good thing - that's how you make those personal 
connections.

I don't have any price info for the "Super-TCXO" but I'd be surprised
if it were crazy, SiTime's other products are all pretty reasonably
priced.

I imagine they got in touch with the manufacturer via the
prominently-displayed email address on the webpage :)  Having the
prospect of buying at least a few reels' worth probably helped too.

I take it they know how to price a gem like that ?

Any ball-park numbers for us ?

Actually a MEMS oscillator, comparison video against quartz TCXO is 
interesting.


Claimed Key Features:
- 30x better dynamic performance for macro cells, small cells, syncE 
and optical networks

- 3e-11 Allan Deviation (ADEV)
- 0.2 ps/mv PSNR, eliminating dedicated LDO
- No activity dips or microjumps
- 10x better dynamic stability, replacing OCXOs in IEEE 1588 
applications

- 1 to 5 ppb/°C frequency over temperature slope
- -40°C to +105°C operation uniquely enables fan-less outdoor 
equipment
- 20x greater vibration resistance ensures continuous system 
operation


Frequency range 1MHz to 220MHz (via 2 product types) so some form of 
synthesizer/divider is inherent.

Looks promising, but with no data sheets and no purchase source or

I can attest that that oscillator was a lifesaver recently in a
project I was tangentially involved with.  They had tried several
TCXOs and were plagued with thermal and vibration sensitivity.  They
dropped in the SiTime and it worked like a charm.
