came across an interesting article in one of my trade journals on the first
commercially available chip scale atomic clock, made by Symmetricum. You can get
further information at: </SPAN></FONT></DIV>

It is quite a remarkable device, taking only 115 milliwatts of power
consumption, with <FONT size=3 face="Times New Roman">two orders of magnitude
better accuracy than oven-controlled crystal oscillators (OCXOs) — and up to
four orders of magnitude better accuracy than temperature-compensated crystal
oscillators (TCXOs). You too can own one for a mere $1500 for the commercial
version in small quantities. It generates 10MHz CMOS level and also has a 1 pps
output.</FONT></SPAN></FONT></DIV>
