DC ELECTRICAL CHARACTERISTICS

(GND = 0 V, all voltages with respect to ground.

PSR_MCLK=12.288 MHz)

Notes:

4. Power Down Mode is defined as PSR_RESET = Low with all clocks and data lines held static.

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

Diagram.
