CS48500 Data Sheet
32-bit Audio Decoder 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 = VDDA = 1.8 V, VDDIO = 3.3 V, GNDD = GNDIO = GNDA = 0 V.
