• Integrates a PLL for frequency synthesis from a single reference input
• Supports multiple output configurations for root complex and switch applications

Applications

• PCI Express root complex designs
• PCIe switch implementations
• High-speed data acquisition systems requiring precise timing

Procurement Notes

Verify the specific ordering suffix to ensure the correct package type and temperature grade match the design requirements. Confirm that the component status is active or recommended for new designs before procurement. Check distributor availability as lead times may vary. Ensure compatibility with the system's reference clock source and power supply specifications.

Selection Notes

Select this component when designing PCIe interfaces requiring low jitter performance and integrated frequency synthesis. Consider the package size and pinout compatibility with the target PCB layout. Evaluate the power consumption against system thermal constraints. Verify that the supported output frequencies align with the specific PCIe generation and link width requirements of the application.
