I agree completely Mark, but...lets play with this a bit more - The 336 design extends the stability limits of a CPU clocking oscillator far beyond the "traditional" clock design, whatever that may, or have been. I would venture the assumption that if the 336 affords stability at frequencies above 120 Mhz, then employing it in processors running below 120Mhz would make for a super stable processor. I'd also venture that since the 336 is a superior design, I would think it would become the standard for incorporation in ANY processor design, regardless of clocking frequency. Perhaps I'm all wet, but if I were a designer and wanted to construct a new processor chip, I'd be thinking of a few things in creation: 1) state of the art operation 2) cost efficiencies in development 3) overall operational stability I think somewhere in those criteria would be some sound rationale for just incorporating 336 into my design, whatever the clocking speed of the processor. It satisfies all elements and does not expose the designer one bit, because it's superior and proven. Parallel it to Autos - the old methods used for air/fuel mix by use of a carburetor have been supersceeded by throttle bodies/fuel injection. FI is prevalent in the design of most new engines, 4 through 8 bangers.... JMHO food for thought, but TPL and Turley know best ;-) Regards
