hi crgwbr and the group

I am also interested in running the SX28 at 100MHz. At this time I am using a 50MHz clock for my application. Upgrading to a 75MHz clock is not an attractive option because the  clock period becomes a not so usefull 13.3333... nS for practical timing applications ! Clocking the SX at 100MHz would result in a very practical 10nS timing increment for my application.

If you need an effective heatsink for your overclocking experiments I recommend using an old PC CPU heatsink/fan assembly if you can fit it onto your board. The 12V fan should provide sufficient cooling with a reduced 9V supply. You may need to mill away some of the aluminium heatsink to fit over your PC board mounted components or use a heat spreader/spacer on top of the SX . I often use this cost effective method to cool expensive power devices in power amplifiers while under developement in the lab.

Does anybody know if Parallax is planning to release a 100MHz SX processor (like the Ubicom part) in the future ? I will buy some if they do.
