9DB202CK-01LF

Overview

The Renesas 9DB202CK-01LF is a jitter attenuator and multiplexer IC designed for PCI Express (PCIe) applications. It operates with a maximum frequency of 140MHz and provides a 1:2 input-to-output ratio. The device accepts differential inputs in HCSL, LVDS, LVHSTL, LVPECL, or SSTL formats and produces HCSL differential outputs. Powered by a single 3.135V to 3.465V supply, it integrates a Phase-Locked Loop (PLL) for clock conditioning. The component is housed in a 20-TSSOP package with a width of 4.40mm and supports surface-mount installation within an operating temperature range of 0°C to 70°C.

Feature Summary

• Jitter attenuation and multiplexing for PCIe clock signals
• Supports multiple input signaling standards including LVDS, LVPECL, and HCSL
• Integrated PLL for low phase jitter performance
• Single 3.3V power supply operation

Applications

• PCI Express (PCIe) clock distribution systems
• Server and workstation motherboard designs
• High-speed data acquisition equipment

Procurement Notes

This component is listed as discontinued by the manufacturer. Verification of availability should focus on distributor surplus stock or secondary market sources rather than direct new production orders. Confirm RoHS compliance status through specific datasheet revisions prior to procurement.

Selection Notes

Select this part when a 1:2 differential clock multiplication or jitter cleaning function is required for PCIe interfaces. Ensure the design accommodates the 20-TSSOP footprint and that the input signal levels match the supported HCSL, LVDS, LVPECL, LVHSTL, or SSTL specifications.

Part Context
