Not sure if those stats are available yet, but IDT has an info page at: http://www.idt.com/?id=6032

It is encouraging and exciting that people are continuing this approach (piezo plus silicon). I wonder what the Q and the impedance of the pMEMS resonator are.

STI offered this ability back in 2007. We tried it on Ethernet devices (15MHz) as a crystal replacement and it worked fine. Plus the drift over the expected lifetime was better than quartz. It was cost that was the hold-up.

IDT will be releasing whole families of tiny pMEMS oscillators throughout 2012.

A tiny, accurate and yet stable oscillator! It seems to be a very good innovation. Is there any short coming? It didn't mention any in the article but I wonder there is something being hid.

Accuracy is not yet specified since actual production devices are not yet announced, but in testing IDT claims drift is just 2 PPM for pMEMS compared with 10 PPM for quartz after 1400 hours at 125 degrees C.

Are these going to replace the crystal oscillators? What is the typical accuracy offered by the pMEMS?

This a good development. These new devices are better suited for industrial and military applications because of their extended temperature range and ruggedness .

NEXT UPCOMING BROADCAST
Why Connect a Car?
May 11, 1pm EDT Monday
Overview: Battle-hardened veterans of the electronics industry have heard of the “connected car” so often that they assume it’s a done deal. But do we really know what it takes to get a car connected and what its future entails? Join EE Times editor Junko Yoshida as she moderates a panel of movers and shakers in the connected car business. Executives from Cisco, Siemens and NXP will share ideas, plans and hopes for connected cars and their future. After the first 30 minutes of the radio show, our listeners will have the opportunity to ask questions via live online chat.
