4.2.2.3 Audio In via USB
4.2.2.4 DAI Input of CS485xx
This feature is currently not supported.
Each of the Audio In Elements listed above are connected to a DAI element. This represent the DAI port
of the DSP. As shown in
CS485xx:
• SCLK Polarity
• LRCLK Polarity
• Temperature Grade - CDB48500s are populated with commercial-grade chips by default
• Reference Clock - Set to the frequency of the crystal driving the CS485XX(Y1). This is the reference
clock is used to determine the clock dividers needed to derive Fs in ADC-only applications. If this
number changes, then all dividers for LRCLK/SCLK will change by the same ratio (e.g.
@24.576 MHz MCLK/512 = 1Fs = LRCLK, @12.288 MHz MCLK/256 = 1Fs = LRCLK.
