CS42418

DC ELECTRICAL CHARACTERISTICS (T

A = 25° C; AGND=DGND=0, all voltages with respect

to ground; OMCK=12.288 MHz; Master Mode)

Notes: 22. Current consumption increases with increasing FS and increasing OMCK. Max values are based on

highest FS and highest OMCK. Variance between speed modes is negligible.

23. ILC measured with no external loading on the SDA pin.

24. Power down mode is defined as RST pin = Low with all clock and data lines held static.

25. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figure .

DIGITAL INTERFACE CHARACTERISTICS (For CQ, T

A = +25° C; For DQ, TA = -40 to +85° C)

Notes: 26. Serial Port signals include: RMCK, OMCK, ADC_SCLK, ADC_LRCK, DAC_SCLK, DAC_LRCK,

ADC_SDOUT, DAC_SDIN1-4 ADCIN1/2

Control Port signals include: SCL/CCLK, SDA/CDOUT, AD0/CS, AD1/CDIN, INT, RST

27. When operating RMCK above 24.576 MHz, limit the loading on the signal to 1 CMOS load.
