DAC and Master Clock Design

[snowpix]

Hello Everyone,

Sorry if my question sounds stupid.

I want to buy a Teac UD-505 DAC which has dual internal master clock 44.1 and 48kHz.
I tried to read about DAC master clock but most of the information are about external master clock and also complicated.

I want to play DSD and 192kHz files through the computer USB, still I didn't get it what master clock is going to do?
Does it mean for converting a 24bit 192kHz file or 11.2 DSD file to analogue sound the master clock act like resample them to 44.1 and 48kHz?

It just has two crystals to support the two main base clocks of 44.1 kHz and 48 kHz for USB input. Any multiple will use the appropriate clock. It's all described in the manual.

There will be no resampling to 44.1 or 48 kHz.

2 x 44.1 gives 88.2 (not that common)
2 x 48 gives 96
4 x 48 gives 192

The internal clock uses multipliers to handle the different sample clocks

wow! Thank you so much, I read a lot about it but always confused. But this is the best way that make me understood about the internal clock.

Sorry but what about DSD when they supposed to play natively not DoP?

DSD is based on 44.1 kHz base rate. Dop or not is irrelevant.

Thank you, so because of this they call it DSD 64 or 128 am I right? 2.8MHz = 64x44.1

Exactly!
