I am going to use the PLL on the the board by just providing a single 16MHz clock from my MCU to the MCLK line (pin 21). Can I just leave BCLK/LRCLK (pins 23,24) floating, or do they need to be grounded or something else?

Thanks.

Hi Paul. So I'm still trying to get the board to come alive. Just trying to send an I2C address writeI am assuming I2C commands to the board can work only with MCLK input?
