Hello,
I'm planning to use the PCM5102A with DVDD = 1.8 V, but I don't know how to connect the XSMT pin.
Reading the datasheet of the PCM5102A there are the following conflicting statements:
- In systems where XSMT is not required, it can be directly connected to AVDD
- AVDD is always 3.3V, so XSMT would be 3.3V, keep that in mind
- External Power Sense Undervoltage Protection Mode is supported only when DVDD = 3.3V.
- so what do I do with the XSMT pin in case of DVDD = 1.8V?
- The XSMT input pin voltage range is from –0.3 V to DVDD+0.3 V
- this conflicts with the first statement for (DVDD = 1.8 V)
- When the XSMT pin level reaches 2 V, soft mute process begins.
- this conflicts with the previous statement for (DVDD = 1.8 V); it would always mute the output
I guess, I have to connect XSFT to ground or DVDD, but the datasheet doesn't mention anything about what to do with this pin in case of DVDD = 1.8 V and I cannot test it for now.
Can you help me, please?
Thank you in advance!
