PLL on the USB Master card. The PLD on the USB Master Card generates SCLK and LRCLK for the DAI
side of the DSP from the MCLK.
On the output side, the CS485xx slaves to MCLK from the USB Master Card and masters SCLK and
LRCLK for the DAC side of the CS42448.The CS485XX always masters its output clocks (DSP_SCLK/
DSP_LRCLK).
