Thanks Rob, Those Canadian $s had me worried there. $2.89 USD is not so bad. --BobG -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]On Behalf Of Rob Robson Sent: Wednesday, August 28, 2002 6:34 PM To: PICLIST@MITVMA.MIT.EDU Subject: Re: [EE]: SPDIF output advice It probably doesn't meet the "inexpensive" criterion, but I've used the Schott 67129600 that Cirrus/Crystal mentions in some of their spec sheets. The Digi-Key part no. is 257-1025-ND, and they go for C$13.96 in singles / 9.38 ea. in tens. Good luck! Rob Robson ----- Original Message ----- From: Robert E.
