Oh, I forgot: Richard Duong BTW, when we were talking about a ckt for use with 3rd OT xtals, Richard asked me what version of the SX "silicon" I was using! Sounds like an iff-fy situation if you have to know that - be interesting to hear whether you can get the SX to oscillate with 3rd OT. best regards, - Dan Michaels Oricom Technologies ===================
