IMI SC462 chip info

[Brad O'Dell]

Does anyone happen to have the pinout for the IMI SC462 clock generator chip?(sometimes the chip is called an IMISC462).  If you do, please send it.  If you have the datasheet, that would be even better.  I know that the IMI product line was acquired by Cypress, and that they have an obsolete products section, but this chip is absent.  I am trying to upgrade a socketed CPU in a laptop.  I need to configure the bus to run at 66MHz instead of 60MHz.  My first step is to substitute a VRT mobile Pentium 133 for a VRT mobile Pentium 120.  Because these both have dual supplies, I hope to insert a Tillamook mobile Pentium MMX 266 in the socket.  MMX chips do not like to be underclocked, so I need the right bus speed.  I also added a trimpot to adjust the Vcore for the new chip.  On a regular motherboard, this Tillamook chip running at the specified 1.9V does not run any hotter than a Pentium 133. I am thankful for any help I can get.   Brad       Thanks, Brad
