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.
