WTD: Datasheets for PMC Sierra modem chips

Hi, I've just been going through a load of old boards that I had occupying space and I'd like to put some of the components to good use. I've already located datasheets for a Motorola DSP56001FE27 digital signal processor I found (time to build an MP3 player!), but a few of the parts have turned up dead ends for data. The parts in question are Sierra Semiconductor (now PMC-Sierra) SC11011CV/ADA, SC11026CN and SC22201CN chips, used on what appears to be an old modem. I've had a look on FreeTradeZone (free? not bloody likely) and the datasheets have been locked (the chips are obsolete). Anyone got PDFs (or paper copies) of these datasheets? I'd like to get these chips doing something (other than taking up valuable space), but it's a bit diffiicult without the datasheets! Thanks. -- Phil. philpem(a)bigfoot.com http://www.philpem.btinternet.co.uk/
