Yep - 27.125MHz is a standard frequency. Divide-by-two gives 13.5625, which= is = 2.5kHz out. Should be close enough though. I'll ring round a few places and = see if I can get my hands on a couple of those. I notice Digikey seem to have the 13.56 crystals, but only in SMD - p/n = XC1358-ND. =A31 each, but with =A322 in handling fees on top of that :( I'll give Quartslab a ring in a bit and get a quote for a custom 13.56 = crystal, but I'm expecting them to cost at least =A310 a piece.. -- = Phil. | Kitsune: Acorn RiscPC SA202 64M+6G ViewFind= er philpem@dsl.pipex.com | Cheetah: Athlon64 3200+ A8VDeluxeV2 512M+10= 0G http://www.philpem.me.uk/ | Tiger: Toshiba SatPro4600 Celeron700 256M+4= 0G -- = http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
