But how the heck did they get some? According to the website, even data
sheets are not available.

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.

The video linked on that page is particularly interesting (if you take
it on face value that they're not faking it. ;) ).

For general group information, as SiTime datasheet is not open to the
public (yet?).

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.
