Additional Details:
The ICS9LPR363DGLF typically operates from a 3.3V power supply. Proper power supply decoupling is essential to minimize noise and ensure stable operation. The device uses a phase-locked loop (PLL) to generate the required clock frequencies from a reference crystal. The specific output frequencies and configurations can be programmed through external control pins and registers. It's crucial to consult the datasheet for detailed programming information and application circuit recommendations to ensure proper operation and compliance with Intel specifications.
The spread spectrum clocking feature modulates the clock frequency slightly to spread the EMI emissions over a wider frequency range, reducing the peak emissions and improving system compatibility. The integrated loop filter components help to stabilize the PLL and minimize phase noise. The device is available in a 48-TSSOP package, which is suitable for high-density board designs.
