Hello, dear experts,

I don't understand enough of the topic, still I want to achieve the best result. What would you recommend me to use for powering a masterclock for my Buffalo DAC project - this LDO

[url=http://www.ti.com/lit/ds/symlink/tps7a4700.pdf[/url]

or a 3,3V Trident Shunt Regulator?

Is it possible to feed the clock (+ Trident or TPS7A4700) from the same Placid HD as the Buffalo DAC? Or would it be necessary to use an extra Placid HD?

Thanks for your help and advice!

Regards,

Florian

The Trident was purpose designed for this application. Why not use that? TSA4700 is an excellent supply, but I would use the Trident in this case.

Okay I will! - Is it possible to mount this Trident Shunt after the Placid HD which supplies also the Buffalo DAC? Or does the DAC have too much influence on the Clock supply then?

I have learnt to treat a clock oscillator as an analog part of a DAC- so is the AVCC Dual Shunt Regulator Module actually the right modul? Or would you really use a Trident Shunt?

Thank you!

Florian
