Part Number: PCM1863 Tool/software: Hello E2E Experts,
Good day.
During my project with PCM1863, I was able to initalize the chip (pll, etc) in a way, that I'm now in Fade In state and I can see the MCLK, SLCK and LRCK signals on I2S bus. But I'm not…
Hi Max,
Max Delius said: In the meantime I could confirm that the noise is induced or at least amplified by radiated EMI from the PSU which is closeby. It seems to be picked up somewhere in the analog front end.
For my understanding, was it basically…
Part Number: PCM1863 Tool/software: Hi,
I have a customer using this device and they are hoping for some clarification for the pin setup as the data sheet lists the following
However, Figures 58, 64, and 66 are all connected to a 2.2uF decoupling cap…
Part Number: PCM1863 Tool/software: My question is when I use PCM1863 EVK with PCC2 software The input signal I want to detect is input by R/L of VIN1 What I do in SLEEP mode is as follows: 1. Write Register 0x70 BIT 1 as 1 >>>Set the mode to SLEEP mod…
Part Number: PCM1863 Tool/software: Hi, I am looking for a solution to wake up my system from sleep state with a digital audio signal. With analog inputs of the pcm1863 it works without any problem using the energysense interupts. Would it be possible…
Part Number: PCM1863 Hello,
My customer wants to use 100uF for VREF and 220uF for VDD as they have found this gives the best audio performance. Are there any issues with these values?
Thanks,
Michael
Hi,
First, in your tests, make sure you are playing a ~1kHz signal at a greater volume than -57 dBFS (or the set threshold level) for the energysense to detect it.
Next, I see in section 9.3.15.2.2 of the datasheet that the INT_STAT register (page 0 0x61…
Part Number: PCM1863 I have a concern about a possible leakage path on my board on the VREF pin. There is the possibility of surface contamination which can create a leakage path thru/around the 2.2uF cap we have from VREF to GND. (The data sheet says…
The SIGDET_INT_INTVL is 4 seconds and written: { PCM186X_SIGDET_INT_INTVL, 0x04 }.
And the SIGDET_SCAN_TIME is 160ms for 50Hz detection: { PCM186X_SIGDET_SCAN_TIME, 0x00 }.
This is the filter design from the TI Biquad Calculator.
And here…
Part Number: PCM1863 Other Parts Discussed in Thread: PCM1860 We are using PCM1863 for audio interface in the I2C mode, where the MD0 is pulled down to set in I2C mode and MD1 is pulled high to set address to 0x96 and DVDD and IOVDD are sorted and supplied…
