NOS DAC with DIR1703 and TDA1541AS2

cartman · 26th August 2005, 04:21 PM

Hi Guys!

I'd like to build a NOS DAC with TDA1541AS2 and I'd like to use the BB DIR1703 receiver IC, because I saw, this IC is better than CS8412/CS8414. (3x lower litter)

I have'nt any schematics...

Can anyone hels me?

Hi,

Because exact jitter spec is lacking, I'd be carefull in judging the spec. In addition, the simple interface between 8412 and 1541 would have my preference

If you want true low jitter, a secondary PLL with VCXO is required. Obviously pin 2 ban 4 of the 1541 should be clocked directly from the VCXO.

best

Thx!

I need a schematic for NOS DAC with CS8414 and TDA1541A and OPA627ap

Please help me!

Have anyone already PCB for sale???

Maybe....
I hope...

Just across the border, a bit to the South, Pedja Rogic has excellent DAC and reclocker boards. They are worth taking the road trip yourself (5-6 hours?).

That is really good solution...

You also have one??

THX!

Mine is with TDA1541A S1 and reclocker board. The sound is very good, and with a proper transport it comes very close to good analog set-up (turntable). It sounds unprocessed compared with other digital sources and serves me very well as a reference DAC when doing modifications. I got DAC and reclocker boards from Pedja, other parts form suppliers around the World.

I have a TDA1541AS2 double crown, and few OPA627...
I'd like to build a good NOS ReClocked DAC.

Which frequency works on your clock?
Can I use the OPA627 instead of original AD844?
Which is better?

Thx!
er.

On Pedjas' site he discusses many of his design choices which is educational in itself as well as answering yours question.
