The 1.09 is for a Turbo z900 (2064-2xx models) The new z990 chips on the MCMs (2084-3xx models) have a cycle time of 0.83ns and the processors are superscalar in design meaning that several instructions may be processed, started, and/or ended at once. For more info, see the z990 Technical Introduction at:

It has a z-900 with 1.09 ns cycle time rated at 918MH. Article can be found at: http://www.research.ibm.com/journal/rd46-45.html The section on first and level packaging.

Take the cycle time (which I believe they do publish somewhere) and invert, and voila. I seem to recall from some comments that Barton Robinson made many months ago that the first generation zSeries boxes were 200Mhz machines (5ns cycle time). I'm sure someone who knows for sure can confirm or refute that.

Run away! Here we go again! IBM doesn't release those kind of specs for the 390 processors.
