9LPRS501SGLF

Overview

The Renesas 9LPRS501SGLF is a single-circuit clock/frequency synthesizer IC designed for Intel CK505 and PCI Express (PCIe) applications. It features a crystal input and provides up to 22 differential clock outputs with a maximum frequency of 400MHz. The device operates on a supply voltage range of 3.135V to 3.465V and includes an integrated PLL. It is housed in a 64-TSSOP surface-mount package and supports an operating temperature range of 0°C to 70°C.

• Integrates PLL for clock synthesis
• Provides 1:22 input-to-output ratio
• Operates within 3.135V to 3.465V supply range

Applications

• Intel CK505 compatible systems
• PCI Express (PCIe) clock distribution
• Embedded system timing

Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Verification of current availability through authorized distributors or alternative sourcing channels is required before procurement planning. Check for valid replacement part numbers if this specific package or suffix is unavailable.

Selection Notes

Select this part for designs requiring a direct replacement for legacy Intel CK505 clock generators in PCIe environments. Ensure the design accommodates the 64-TSSOP footprint and the specified 3.135V-3.465V power rail. Verify that the 0°C to 70°C commercial temperature range meets the system's environmental requirements.

Part Context

The 9LPRS501 series belongs to Renesas' portfolio of application-specific clock generators. This model specifically targets high-speed serial interface standards like PCIe, offering multiple differential outputs from a single crystal reference to simplify board layout and reduce component count compared to discrete solutions.

Replacement Considerations

As the product status is marked as obsolete, verify compatibility with newer Renesas PCIe clock generators such as the 9ERS3165B or similar CK505-compatible successors. Confirm pinout and electrical parameter alignment before substitution.
