D2-926XX_14 Datasheet, PDF (8/38 Pages) Intersil Corporation – Intelligent Digital Amplifier and Sound Processor

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)

NOTES:
9. All input pins except XTALI.
10. Input leakage applies to all pins except XTALO.
11. Power-down is with device in reset and clocks stopped.
12. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
13. Analog performance is system-design dependent and is affected by factors that include PCB layout, shielding and routing of analog traces, additional
components within the analog input path, and power supply isolation.
