Part Number: PCM5122 Hi team,
My customer plans to use the sampling frequency of 88.1kHz and concerns the delay time of each filter. For example, In case of NORMAL (8x) filter when fs=48kHz, delay time coefficient is 20. Is 20 also applicable in case…
Shenghao, I will check this, however the above test is being performed with the DAC in hardware mode without the driver connected via i2c in the dts, it performs the same way in hardware mode as it does with the i2c / pcm512x driver connected. Pops occur…

Part Number: PCM5122 When using purepath console, I am wanting to get a dump of registers with default settings. Before dumping and looking at the registers, it appears that certain bits are highlighted as modified values as seen on the pictures below…
Part Number: PCM5122 Dear,
We probably have a problem with the PCM5122. The PCM5122 DAC works fine and have a signal on the 2 outputs. To check the status of the DAC we read every second register 118 and see that the DAC is always in state "Volume ramp…
Part Number: PCM5122 Dear sir,
I have some questions about PCM5122 THD+N and SNR chart!
Here are the charts for THD+N and SNR.
Please help to give me some advice.
Thanks.
1. THD+N:
-> what is the THD+N actually? Around 50dBV+ 5.9dBV?
2. SNR:
->…

Part Number: PCM5122 Other Parts Discussed in Thread: PUREPATHSTUDIO Hello,
Because we saw interpolation points on 15Khz with 8 bit interpolation we wanted to increase to 16x interpolation, but we get bad results when we enable it (register 34, bit 4…

Hi Team,
Using the PCM5122 with a TDM (3wire) bus and the clock signals BCLK and SCLK are 12.288MHz. (8 x 32bit at 48Khz) The PLL is disabled at this moment
This works fine with an 8x interpolation settings (register 31 bit I16E =…
Part Number: PCM5122 Other Parts Discussed in Thread: PCM5102A , Hi Team,
My customer want to change design from PCM5102A to PCM5122. I checked datasheet and the different is interface only. May I know if customer change solution to PCM5122, they need to change…
