9 / 81 page  DS632PP1 9 CS44800 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.) 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. ILC measured with no external loading on the SDA pin. 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. DIGITAL INTERFACE CHARACTERISTICS (GND = 0 V, all voltages with respect to ground) 10. Serial Port signals include: SYS_CLK, DAI_MCLK, DAI_SCLK, DAI_LRCK, DAI_SDIN1-4 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] Parameter Symbol Min Typ Max Units Normal Operation (Note 4) Power Supply Current (Note 5) VD = 2.5 V VDX = 3.3 V VDP = 3.3 V VLS = 3.3 V VLC = 3.3 V (Note 6) ID IDX IDP ILS ILC - - - - - 150 2 1.2 150 250 - - - - - mA mA mA µA µA Power Dissipation VD=2.5 V, VDX = VDP = VLS = VLC = 3.3 V - 387 500 mW Power Supply Rejection Ratio (Note 7) (1 kHz) (60 Hz) PSRR - - 15 40 - - dB dB Power-Down Mode (Note 8) Power Supply Current All Supplies except VDX (Note 9) Ipd -80 - µA Parameters (Note 10) Symbol Min Typ Max Units High-Level Input Voltage XTAL PWM Interface Serial Audio Interface Control Interface VIH 0.7xVDX 0.7xVDP 0.7xVLS 0.7xVLC - - - - - - - - V V V V Low-Level Input Voltage XTAL PWM Interface Serial Audio Interface Control Interface VIL - - - - - - - - 0.2xVDX 0.2xVDP 0.2xVLS 0.2xVLC V V V V High-Level Output Voltage at Io = -2 mA PWM Interface Serial Audio Interface Control Interface VOH VDP-1.0 VLS-1.0 VLC-1.0 - - - - - - V V V Low-Level Output Voltage at Io = 2 mA PWM Interface Serial Audio Interface Control Interface VOL - - - - - - 0.45 0.45 0.45 V V V Input Leakage Current Iin -- ±10 µA Input Capacitance - - 8 pF |
