10 / 26 page CS48DV2B Data Sheet 32-bit Audio DSP for Dedicated Dolby Volume and Audistry by Dolby 10 Copyright 2009 Cirrus Logic DS875F2 CONFIDENTIAL 5. Characteristics and Specifications Note: All data sheet minimum and maximum timing parameters are guaranteed over the rated voltage and temperature. All data sheet typical parameters are measured under the following conditions: T = 25 °C, CL = 20 pF, VDD = VDDA = 1.8 V, VDDIO = 3.3 V, GNDD = GNDIO = GNDA = 0 V. 5.1 Absolute Maximum Ratings (GNDD = GNDIO = GNDA = 0 V; all voltages with respect to 0V) Caution: Operation at or beyond these limits may result in permanent damage to the device. Normal operation is not guaranteed at these extremes. 5.2 Recommended Operating Conditions (GNDD = GNDIO = GNDA = 0 V; all voltages with respect to 0V) Note: It is recommended that the 3.3 V IO supply come up ahead of or simultaneously with the 1.8 V core supply. 5.3 Digital DC Characteristics (Measurements performed under static conditions.)
