> Magnus, Randy, > I hope NO ONE is using a 4046 in any contemporary CD player designs! I couln't agree more! :o) For some applications, the 4046 is right on the money, but for quite alot of applications you don't even want to be near it. At one time did an engineer try to use a 4046 at the firm, just as a phase-detector. It didn't work very well and in the end the 74HCT00 based phase-detector that I had originally proposed was implemented and worked perfectly and well within specs. The trick about doing cheap designs is knowing which corners one should cut and which to not cut. The designed locked a 155,52 MHz clock to a 8 kHz reference and that was in another staged stepped up 16 times to 2,48832 GHz to clock the data, the SDH/SONET jitterspecs where met. BTW, do you happend to have the old Oncore documents lying around? See my querry for them not too long ago. I want as much hard facts on the GPS in my Z3801A.
