asynchronous reclocking and low jitter clocks
 
Hi

I am new to diy hifi, and electronics in general! (i studied Geography at uni!)

In modding my cd player I am about to start work on replacing the standard clock. I have studied many of the forums but i need something cleared up.

>Are asynchronous reclocking and a separate low jitter clock completely separate concepts?

>further, if this is correct which configuration is best?

-old clock / no asynchronous reclocking (cdp standard)
-old clock / asynchronous reclocking
-new clock / no asynchronous reclocking
-new clock / asynchronous reclocking

Asynchronous reclocking is an easier option for me because i cannot source 11.2896 Mhz crystal osciallators in the UK! Whenever I find any they are out of stock ! :(


Cheers,

Ash.

You can build a low jitter clock yourself, with your cd player's crystal and some circuitry around it, like the kwak clock

what's your cd player/dac?

I'm not sure about it, but assynchronous reclocking is of limited use for I2S. Yet to confirm

Hi,


I have a few that im experimenting on:-

Mission pcm7000 (tda1541/saa7210 )

Philips CD471 (tda1541/saa7210 )

DPA little bit (Saa7350/ ym3623)

Philips cd723 (erm TDA1545 i think)


Probably will work on the Mission!


Cheers,


Ash.

Hi

There is many options to roll your own clock
