9SQL4952CNLGI8

Overview

The 9SQL4952CNLGI8 is a PCIe-compliant clock generator manufactured by Renesas Electronics. It operates within a supply voltage range of 3.135V to 3.465V and supports a maximum frequency of 25MHz. The device features one circuit with a 1:4 input-to-output ratio, providing differential clock outputs while lacking differential inputs. Designed for surface mount installation, it utilizes a 32-VFQFPN package (5x5mm) with an exposed pad. The component functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• PCI Express compliant clock generation
• Single circuit with 1:4 output ratio
• Differential clock outputs
• 32-VFQFPN (5x5mm) package

Applications

• PCIe platform clock distribution
• Server motherboard timing solutions
• Industrial control systems requiring PCIe compliance

Procurement Notes

Verify the specific suffix CNLGI8 against official Renesas documentation to confirm pinout and configuration details. Check current lifecycle status as timing components frequently undergo obsolescence notices. Ensure moisture sensitivity level handling procedures are followed during assembly to prevent package damage.

Selection Notes

Select this component when a dedicated 25MHz PCIe reference clock with four differential outputs is required. Confirm that the 3.3V nominal supply voltage aligns with the system design. Verify that the 32-VFQFPN footprint fits the PCB layout constraints compared to alternative packages like VFQFN or QFN variants.

Part Context

This part belongs to Renesas' portfolio of application-specific clock generators tailored for high-speed interface standards. It serves as a critical timing source for peripheral devices connected via PCIe lanes, ensuring signal integrity and synchronization across the bus architecture without requiring external jitter attenuators.

Replacement Considerations

Consult Renesas datasheets for direct cross-references within the 9SQL series. Verify electrical compatibility and pin assignments before substituting with other PCIe clock generators from different manufacturers.
