I have a question about PCM5242EVM.
In this board in RC1 there is a 0 Ohm. I want to use VCOM mode instead VREF mode. I changed in the RC1 0 Ohm with 1uF.
With PurePath console 2 I set this registers:
1. Page 0 / Register 2 RQST = 1: Standby mode
2. Page 1 / Register 8 RCMF = 1: Fast ramp up → on
3. Page 1 / Register 9 VCPD = 0: VCOM is power on
4. Wait 3ms with external capacitor = 1μF
5. Page 1 / Register 8 RCMF = 0: Fast ramp up → off
6. Page 1 / Register 1 OSEL = 1: VCOM mode
7. Page 0 / Register 2 RQST = 0: Normal mode
I have on the VCOM pin nearly 1.2v but on the output the signal is still with zero offset. I expect VCOM offset also on the XLR connector.
Where is my mistake?
Thank you for answer,
Giovanni Chiparo
