Part Context

This component belongs to the Renesas 9LPRS series of clock generators. These devices are engineered as direct replacements or derivatives for the industry-standard Intel CK505 clock synthesizer, ensuring compatibility with existing motherboard designs that rely on this specific timing architecture.

Replacement Considerations

Verify pinout compatibility with the original CK505 implementation. Ensure the PCB layout supports the 64-TSSOP package dimensions (17.0mm x 6.1mm). Confirm that the thermal requirements align with the 0°C to 70°C commercial grade specification.
