Tool/software:
Currently we are applying 1412 kb/s, 44.1KHz, 16 bits, 2ch, FLAC signal on the RXIN2 input of PCM9211 IC.
After configuring the IC we are getting no output on the main output port. Upon inspecting, we found that PLL is not getting a lock and registers 0x38 and 0x39 are showing values of 80h.
Below are the setting we performed after startup,
Reg -> Value
0x40 -> 0xE2 (Disable ADC and DIT)
0x6B -> 0x11 (DIR as main port source)
0x34 -> 0xC2 (RXIN2 as DIR source)
0x37 -> 0x00 (This is default value but i tried it either way)
0x26 -> 0x81 (Tried changing the ADC clock source even though ADC was turned off)
0x30 -> 0x12 (Enable PSCKAUTO to autoselect PLL SCK)
Using stm32f401RCT6 MCU as DSP and using DMA in circular mode to receive data over i2s protocol.
PCM9211 schematic is attached.
