D2-926XX Datasheet, PDF (6/37 Pages) Intersil Corporation – Integrated DSP Digital Sound Processing

D2-926xx
Electrical Specifications T_A = +25°C, CVDD = PLLVDD = 1.8V ±5%, RVDD = PWMVDD = 3.3V ±10%. All grounds at 0.0V. All voltages
referenced to ground. PLL at 294.912MHz, OSC at 24.576MHz, core running at 147.456MHz with typical audio data traffic. Minimum supply currents are
measured in full power down configuration. (Continued)
