Where do you buy these ? Their web site was not too illuminating.
digikey and mouser carry a lot of SiTime parts, including eval boards.
Tnx, Dick, W1KSZ

Hello, time Nutters--
I have been phase locking the freq counters in my HP 6-GHz VNA, Tektronix
spectrum analyzer and bench freq counter to the 10 MHz signal from
a Trimble Thunderbolt via a 4-port distribution box and long coax cables
to each of the instruments. This works well but is a pain in the tush
connecting to long coax cables when the bench test gear are moved around.
A friend suggested looking into some MEMS TCXO's made by SiTime to
do this with. SiTime offers a wide variety of Stratum-3 TCXO chips. One
of them is the SiT5358 which is spec'd at 0.05 ppm from 1 to 60 MHz.

I am wondering what any feedback thoughts might be on this from
the Time-Nuts gang? An eval-PCB board for the SiT5358 chip is
available. What say the Time-Nutters gang about this approach for
incorporating a small SiT5358 eval-PCB board into my bench test
gear for phase locking to? I am also wondering which of the
SuperStratum3 TCXO chips might be the best choice for a project
like this?
Any feedback on this is most welcome!
