Zero delay buffers & jitter

Gluca · 20th February 2006, 06:43 PM

Did anyone have the chance to read the paper from Cypress on zero delay buffer and jitter reduction?

I searched here and there on DIYAudio but I could not find any comment on the paper and these buffers.

I can't say I am an expert but err... it seems interesting ... doesn't it?

Looks like the link is broken... But it's definitely interesting

.

I am redesigning my NPC SM5847/SM5865 DAC using CY23FS04 DCXO for clock clean-up. Cypress claims 55db jitter reduction at audio frequencies (see their application note)!

OK. you got the corret link to the same Application Note I was referring to.

Nice PCB & project! Congrats. I'll study your schematics.

I am designing my first DAC (CS8414 + 2x BB1794 mono-operated) and I was planning to use that Cypress buffer for the clock.

Anyone else out there?

Hi.

Reading the application note, this is like manna from heaven !!!

I am surprised that the great clock-makers on this forum have not picked it up ! ( or maybe they have ?? )
