5V41068APGGI

Overview

The 5V41068APGGI is a PCI Express clock buffer and multiplexer IC manufactured by Renesas Electronics. It features a 2:1 input-to-output ratio with one differential output. The device supports maximum frequencies of 200MHz and operates on a supply voltage range of 3.135V to 3.465V. It utilizes HCSL inputs and provides HCSL or LVDS outputs. The component is housed in a 16-TSSOP package and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Supports 2:1 differential clock multiplexing for PCIe applications
• Provides low additive jitter suitable for high-speed data transmission
• Offers flexible output interface options including HCSL and LVDS

Applications

• PCI Express Gen1/Gen2/Gen3 clock distribution systems
• High-performance server and storage backplanes
• Telecommunications infrastructure requiring precise timing

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Procurement should focus on verifying stock availability through authorized distributors, as new production has ceased. Buyers must confirm the specific revision status and ensure compliance with RoHS3 standards before finalizing acquisition plans.

Selection Notes

Engineers selecting this part should verify compatibility with existing PCIe generation requirements, specifically regarding jitter performance limits. The fixed 2:1 mux architecture and single output configuration must align with system topology. Designers must account for the specific 3.3V supply tolerance and thermal constraints inherent to the TSSOP-16 package.

Part Context

The 5V41068A belongs to the IDT/Renesas FemtoClock family of precision clock generators. This series targets high-speed serial communication standards where signal integrity is critical. The device integrates multiplexing capabilities directly into the clock buffer, reducing component count compared to discrete solutions.

Replacement Considerations

As the 5V41068APGGI is discontinued, engineers should evaluate alternative clock muxes from the same product family that maintain pinout compatibility. Verify that substitute components support identical PCIe generations and output voltage levels to ensure seamless integration without board redesign.
