Most DAC's are capable of variclock. What you don't have in the A5348 is a continuous analog reconstruction filter. It may work if you wanted restricted range of variclock, but if you want -30/+40%, it's gonna be a problem.niklasni1 said:Yes. For a variable clock system it's more appropriate, though, since you can actually vary the clock
I think you answered my question, though: the write interface is more than capable of keeping up with 8x 125ksps, but the DACs take 8µs to settle -- which is where the 125ksps figure comes from, I'd think --, so it should be fine for 8 channels of <50khz.
That's exactly what I wrote. You're gonna need an external filter. This filter will be fixed at the lowest Nyquist frequency. Is that suitable for your application?niklasni1 said:I was under the impression that the 5348 does no filtering, and thus needs an external reconstruction filter?
OK. Your application was not clear so it was a tad difficult to answer. Now it's better.niklasni1 said:It's for a sampler. It'll have a voltage-controlled effect filter that also acts as a reconstruction filter, like the Akai S900 or the Shruthi synthesizer.

don't forget, audio converters do little to spec DC performance.
if its a control voltage for a VCA etc, then it'll need decent DC performance.
