Dc Electrical Characteristics; Digital Interface Characteristics - Cirrus Logic CS44600 Manual

DC ELECTRICAL CHARACTERISTICS

(GND = 0 V, all voltages with respect to ground; DAI_MCLK = 12.288 MHz, XTAL = 24.576 MHz, PWM Switch
Rate = 384 kHz unless otherwise specified.)
Normal Operation (Note 4)
Power Supply Current (Note 5)
Power Dissipation VD=2.5 V, VDX = VDP = VLS = VLC = 3.3 V

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-
tween DAI clock rates is negligible.
6. I measured with no external loading on the SDA pin.
LC
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.
