Nice work, thanks for sharing.
This might be the most expensive way to do it, though! The AD1895 is $6, and the WM8804 is $7, so that's a lot of added cost.
Curious - why didn't you have the ADAU1701 be a clock slave from the WM8804, so you wouldn…
I have questions about SRC AD1895.
In the data sheet, we can find following descriptions.
Under what conditions does the device detect the change in a sample rate ?
I afraid that unexpected MUTE occurs during the audio data playback …
Thanks Bob, I will read AD1895 datasheet, hope it will help.
I have ADAU1701 (256*fs 96kHz) with AD1895 (output master mode 256*fs, up to 96kHz) upsampler.
Should I use one generator 24.576MHz for both MCLKI ADAU/AD input or should I use two separate local oscillator?
Two independent local oscillator make…
I need to use AD1895 devices in TDM mode.
In this mode, for example, if there are 4 devices and one of the devices in the chain them does not get an input, then how would this be taken care in the output?
When external clock signal is supplied to MCLK_I pin of AD1895/96, how much jitter is acceptable for proper operation?
Is any performance or implementation data available for the ASRCs on these SigmaDSP parts such as THD, DNR, or FIR taps/group delay? If not, I notice the supported ratios match the AD1895/AD1896---is it reasonable to use, say, the AD1895 as a proxy? Since…
Is it possible to use AD1895 only as a jitter attenuator of the incoming signal (S/PDIF from CD player or from other source converted to I2S on WM8804), with bit-perfect and without any resampling?
In this way (1:1 fs out to fs in ratio):
On the ADAU1701, the serial port rate should be running at the same rate as the SigmaDSP core. In order to connect two devices running at different sampling rates, you would need to use a sample rate converter (SRC) between the two serial ports. The AD1895…
