This isn’t my area of expertise, but from reading the datasheet I’ve gotten the following: You should be able to get the chip to work over a wide range of sample rates by varying the clock. Ok, just wanted to confirm that. Results 1 to 4 of 4. By using our datashdet, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Teensy – I2s object – CS DAC – Aliasing

How to use nonstandard audio sample rate data with audio DAC? I got a capacitance of 5nF for an RL of 1k ohm. Doodle 1, 4 Your schematic shows C4 at 4. Email Required, but never shown. In Table 1 the CS data sheet states that it accepts standard audio sample rates in kHz of 32, Surely the details of that are to be found in the datasheet if you read it carefully. Probably also wants to be a NP0 ceramic or good cd4334 plastic film type where the capacitance is highly stable as the voltage changesnot X7R ceramic or electrolytic where the capacitance varies with voltage.

But there’s a problem for square and sawtooth waveforms, I can clearly hear aliasing artifacts that get worse the higher the frequency normal for aliasing and it’s annoying the hell out of me.

Post as a guest Name. I only briefly looked at the datasheet. It showed the table which made me confused but I have my answer.

What does one do to get correct output if the audio data sample rate is not one of these number or is less than 32kHz?

How do I deal with this? Oh yeah, i forgot to update the schematic, messed up the calculations when i designed it at first Right now i have a nF capacitor for C4, because it’s all i had laying around. Is there anything in the I2s object that could be improved or is it in the Waveform modulated object? Sign up using Facebook. Sign up using Email and Password.

But the equation on page 4 in the CS datasheet seems to say that capacitor ought to be in the darasheet to 6 nF range. So C4 should be around 3. I’ve included my circuit schematic, CS datasheet and a node diagram of my audio system. Again, I didn’t read the details, but it certainly appears to be synchronous to that clock.

All times are GMT. Olin Lathrop k 30 I can hear the aliasing at around hz and up with the square wave. Home Questions Tags Users Unanswered. There also appears to be some choice of scaling internal to the chip for a given clock. What I gather from that is that as long as you match your master clock to your input frequency the chip sets the internal dividers itself.

This chip has a clock input called MCLK.
