DIGITAL FILTER CHARACTERISTICS

Notes:

6.

Response shown is for Fs equal to 48 kHz. Filter characteristics scale with Fs.

DC ELECTRICAL CHARACTERISTICS

GND = 0 V, all voltages with respect to 0 V. MCLK=12.288 MHz; Master Mode.

Notes:

7.

Device enters power-down mode when MCLK is held static.

8.

Valid with the recommended capacitor values on FILT+ and VQ as shown in the Typical Connection

Diagram.
