Hi,
I need please some advices about the way to go or not with clocks for a DAC or tweaking CDplayer.
If I understand a good clock is for the most important things, please correct me if i'm wrong:
- good quality of the crystal oscillator
- clean power supply
- stable voltage
- layout : very short traces between components/crystal and dac and good choice about caps.
So I know, i can't go wrong with a tentlabs, diy kwak n°?... but is it always good to tweak already in place clock in a old Cd players like the Philips or Marantz? Old crystal oscillator have advantage : good stability ?
For a DIY DAC, what is a good brand for crystal oscillator (Tentlabs, but what else ?) if i want to do myself the most simple clock :
crystal oscilator : VCXO, TCXO (do i really need that?) : which brand for quality ?
stable voltage : LT-1236 (noise< 1ppm) high precision, 5V
clean voltage : batery, which type ? (low resistive), my idea i for a 1,8 V clock( for ECdesign project)
layout, caps : sanyo SEP but Can i do alone an enough goog layout.
Sorry for the number of questions, but tell me if the ideas are just naives (I'm not a tech) but I want to understand if it's possible to have a good clock with a battery/cells and better than a regulated one from an alone transformer power supply with good reg à la Dexa or others? Maybe cheaper (but no compromise with quality parts).
Or i forget the 1,8 V clock and i go for a easy solution with ian FiFO... but do i need that for a multibit DAC like the AD 1865 or TDA1541, PCM56...?
thanks for your answers or designs, and forget if the que question is too large.
. Not a problem if you hijack this thread for sharing about the upon ideas about the pertinence of the clock design in the final result of the good sounding of a DAC... asIi know nothing I can just learn here !
