4. Normal operation is defined as RST = HI with a 997 Hz, 0 dBFS input.
5. Current consumption increases with increasing XTAL clock rates and PWM switch rates. Variance be-
6. I
7. Valid with PSRR function enabled and the recommended external ADC (CS4461) and filtering.
8. Power down mode is defined as RST pin = LOW with all clock and data lines held static.
9. When RST pin = LOW, the internal oscillator is active to provide a valid clock for the SYS_CLK output.
10. Serial Port
tween DAI clock rates is negligible.
Control Port signals include: SCL/CCLK, SDA/CDOUT, AD0/CS, AD1/CDIN, INT, RST, MUTE
PWM signals include: PWMOUTA1-B4, PSR_MCLK, PSR_SYNC, PSR_DATA, PS_SYNC, GPIO[6:0]
LC
measured with no external loading on the SDA pin.
