9DB202CGLFT

Overview

The Renesas 9DB202CGLFT is a PCI Express jitter attenuator and multiplexer IC designed for high-speed serial link applications. It features an integrated Phase-Locked Loop (PLL) to reduce input clock jitter while maintaining signal integrity. The device accepts differential inputs including LVDS, LVPECL, HCSL, LVHSTL, and SSTL, converting them to a single differential HCSL output. Operating at a maximum frequency of 140MHz with a supply voltage range of 3.135V to 3.465V, it is housed in a 20-TSSOP package. This component supports PCIe Common Clocked architectures by providing precise clock distribution.

Feature Summary

• Integrated PLL-based jitter attenuation for PCI Express compliance
• Supports multiple input formats: LVDS, LVPECL, HCSL, LVHSTL, SSTL
• Single differential HCSL output optimized for PCIe loads
• Maximum operating frequency of 140MHz
• Available in a compact 20-TSSOP surface-mount package

Applications

• PCI Express (PCIe) root complex clock generation
• Jitter reduction for high-speed serial data links
• Clock distribution in server and storage systems
• PCIe endpoint device clocking

Procurement Notes

Verify the specific suffix 'GLFT' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Note that this component may be subject to End-of-Life (EOL) notices; check official Renesas Product Change Notifications (PCN) for availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when a low-jitter, single-output HCSL clock is required from various differential input sources for PCIe Gen 1 or Gen 2 interfaces. Ensure the input clock frequency does not exceed 140MHz. Verify that the system power supply remains within the 3.135V to 3.465V range to maintain timing specifications.

Part Context

The 9DB202CGLFT belongs to the Renesas 9DB202 family of PCIe jitter attenuators. It serves as a specialized clock conditioning solution distinct from standard clock buffers or generators. The part is engineered specifically to meet the stringent jitter requirements of PCI Express standards, differentiating it from general-purpose timing ICs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Renesas technical support for direct replacements or verify if newer revisions of the 9DB202 series offer equivalent functionality.
