Procurement Notes

Verify the specific ordering suffix 'PAHR' corresponds to the required tape-and-reel packaging and temperature grade. Confirm that the 52-TQFP footprint matches the target PCB design. Ensure compatibility with 3.3-V logic levels in the receiving circuitry. Cross-reference the manufacturer's latest datasheet revision to confirm pinout integrity and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a single-chip solution for generating and distributing low-jitter clocks is required. It is suitable for designs needing multiple synchronized outputs derived from a single reference. Consider the thermal performance of the TQFP package if high ambient temperatures are expected. Evaluate power consumption requirements against the device's active current specifications.

Part Context

This part belongs to the CDC2586 series of PLL-based clock drivers. It is designed to replace older discrete clock buffer solutions. The device simplifies board layout by integrating frequency synthesis capabilities. It is commonly used in applications requiring precise timing alignment across multiple subsystems.

Replacement Considerations

Consult official substitution guides for compatible parts within the same family. Verify pin-to-pin compatibility if replacing existing inventory. Ensure functional equivalence regarding jitter performance and output drive strength.
