CS49DV8C Data Sheet
32-bit Audio DSP Family
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 = 1.8 V,
VDDA = VDDIO = 3.3 V, GNDD = GNDIO = GNDA = 0 V.
5.1 Absolute Maximum Ratings
(GNDD = GNDIO = GNDA = 0 V; all voltages with respect to 0 V)
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 0 V)
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.)
