Analog Devices make several, one of which Brook Shera used in his GPS
disciplined reference oscillator. I obtained a couple as samples from AD for
nothing. Part number is PCM61P on the original circuit, and the AD
equivalent is AD1861N. It is actually an 18 bit device now I look at the
documentation, but check out their website.

Maxim also do such devices, and provide samples. However I suspect you may
find that most will be more than 16 bits as the prime market is CD players
and DVDs.
