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…
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 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
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…
Hey Bhuvan,
A couple things to note:
When pulling up the i2c lines, use 2.2kOhms
Ensure you are in fact using the PCM1863 and not a hardware controlled version from this family of parts (pcm1860/61)
Confirm all your connections are correct. Make sure…
Part Number: PCM1863 Hi LPA team,
My customer is asking if the start-up of this IC.
Is it fine to hold the MS pin as low when booting the IC?
The datasheet indicates below.
Thanks,
Luke
Part Number: PCM1863 Hello,
On the datasheet, Section 7.11 Timing Requirements.
(1) tBCKL min is 1.5x tSCKI.
In our customer's usage is I2S slave mode with PLL BCK input.
At this case, SCKI is not used but internal PLL generate SCK.
Should we convert…
