CS4525

SERIAL AUDIO INPUT PORT SWITCHING SPECIFICATIONS

AGND = DGND = PGND = 0 V; TA = 25°C; VD = 3.3 V; Inputs: Logic 0 = DGND; Logic 1 = VD.

Notes:

8. FCLK is the frequency of the crystal connected to the XTI/XTO pins or the input SYS_CLK signal.

9. Nbits is the number of bits per sample of the serial digital input.

10. After powering up the CS4525, RST should be held low until the power supplies and clocks are stable.
