TS2PCIE412RUAR

Analog Switches - Special Purpose Overview

The TS2PCIE412RUAR is a passive FET switch from Texas Instruments designed for PCI Express applications. It supports data rates up to 8 Gbps with a maximum clock frequency of 1.25 GHz. The device features two lanes and two ports, operating within a supply voltage range of 1.5 V to 2 V. It exhibits a propagation delay of 0.28 ns and functions reliably across an extended temperature range from -40°C to +85°C. The component is housed in a WQFN-42 package suitable for surface mount installation.

Analog Switches - Special Purpose Feature Summary

• Passive FET switching architecture for low insertion loss
• Supports PCIe Gen1 and Gen2 signal integrity
• Compact WQFN-42 package for space-constrained designs

Analog Switches - Special Purpose Applications

• PCI Express signal routing
• System board interconnects
• Peripheral expansion slots

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix RUAR against official datasheets to confirm the WQFN-42 package and tape-and-reel delivery format. Ensure compatibility with the required 1.5 V to 2 V supply rails and check RoHS compliance status through manufacturer documentation before integration into production assemblies.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring passive switching for PCIe lanes with minimal power consumption. Verify that the 1.25 GHz bandwidth meets the system's signaling requirements. Confirm that the WQFN-42 footprint aligns with available PCB real estate and thermal management capabilities.

Analog Switches - Special Purpose Part Context

This part belongs to the TS2PCIE412 series of interface ICs. It serves as a signal path selector within the broader portfolio of Texas Instruments PCI interface solutions. The device complements active redrivers and retimers by providing a simple, low-power switching mechanism for lane selection.

Analog Switches - Special Purpose Replacement Considerations

Consult official substitution guides for equivalent passive switches. Verify pinout compatibility and electrical specifications such as on-resistance and bandwidth before considering alternative components.
