Description. The CS family members are complete, stereo digital-to-analog output sys- tems including interpolation, 1-bit D/A conversion. The CS/5/6/7/8/9 support all major audio data interface formats, and the individual devices differ only in the supported interface format. The CS family members are complete, stereo digi- package. The CS/ 5/6/7/8/9 support all major audio Figures of the CS/8/9 datasheet.

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. It showed the table which made me confused but I have my answer. Your schematic shows C4 at 4. Again, I didn’t read the dafasheet, but it certainly appears to be synchronous to that clock.

Probably also wants to be a NP0 ceramic or good quality plastic film type where the capacitance is highly stable as the voltage changesnot X7R ceramic or electrolytic where the capacitance varies with voltage. Olin Lathrop k 30 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?
But there’s a problem for square and sawtooth waveforms, Adtasheet can clearly hear aliasing artifacts that get worse the higher the frequency normal for aliasing and it’s annoying the hell out of me. Ok so I’ve made an 8 voice poly synth with four choosable waveforms, 2 operator FM and a selectable 8 voice karplus strong synth. So C4 should be around 3.

There also appears to be some choice of scaling internal to the chip for a given clock. I got a capacitance of 5nF for an RL of 1k ohm. You should be able to get the chip to work over a wide range of sample rates by varying the clock. This isn’t my area of expertise, but from reading the datasheet I’ve gotten the following: All times are GMT.
In Table 1 the CS data sheet states that datzsheet accepts standard audio sample rates in kHz of 32, 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.
