TMUXHS4512RETT

Overview

The TMUXHS4512RETT is a high-speed bidirectional passive switch in mux or demux configurations. It supports data rates up to 20Gbps and operates on a single 1.8V supply voltage (1.62V to 1.98V). The device features four differential channels with a typical –3dB bandwidth of 13.0GHz and an on-state resistance of 8.8Ω. Sideband pins are 5.5V tolerant, supporting control logic voltages of 1.2V, 1.8V, and 3.3V. Active power consumption is 500μA, while standby power is 2μA. It includes IOFF protection against current leakage when the supply rail collapses. The component is housed in a 40-pin WQFN package measuring 3mm x 6mm with a 0.4mm pitch.

Feature Summary

Protocol-agnostic design supporting USB4, Thunderbolt 3/4, and DisplayPort 1.4/2.1 interfaces
Integrated charge-pump technology for low on-state resistance and high bandwidth
IOFF protection prevents back-powering and leakage during supply rail collapse
Supports both differential and single-ended signaling within specified voltage limits

Applications

PC and notebook internal display switching
Switchable graphics between integrated and discrete GPUs
DisplayPort source and sink selection in docks and monitors
Data center and enterprise computing infrastructure
Wireless infrastructure and electronic point of sale systems

Procurement Notes

Verify the specific suffix RETT corresponds to the commercial temperature range (0°C to 105°C) rather than the industrial variant (-40°C to 125°C). Confirm the package type matches the 40-pin WQFN specification. Ensure ESD handling procedures are followed due to the sensitivity of high-speed analog switches. Cross-reference the ordering part number with the manufacturer's latest documentation to confirm availability and revision status.

Selection Notes

Select this component for applications requiring protocol-agnostic switching at data rates up to 20Gbps. Ensure the system power supply remains within the 1.62V to 1.98V range for optimal performance. Verify that the common-mode voltage of the high-speed signals stays within the 0V to 1.0V limit. Consider the thermal characteristics and layout requirements for the exposed thermal pad to maintain signal integrity and device reliability.

Part Context

This device belongs to the TMUXHS4512 family of high-speed multiplexer switches. It is designed as a generic analog differential passive mux/demux suitable for various high-speed interfaces. The RE suffix indicates the WQFN package, while TT denotes the reel packaging format. It serves as a critical interconnect solution for managing multiple video and data sources in compact electronic designs.
