PI3USB31531ZTFAEX

Analog Switches - Special Purpose Overview

The PI3USB31531ZTFAEX is a 6:4 differential channel bidirectional crossbar switch designed for USB Type-C applications. It supports USB 3.1 Gen2 signals at 10Gb/s and DP 1.4 signals at 8Gb/s. The device features low insertion loss of -3dB and return loss of -8dB at 10Gb/s. It operates on a 3.0V to 3.6V power supply within an industrial temperature range of -40°C to 85°C. The component is housed in a 40-contact UQFN (ZTFA) package.

Analog Switches - Special Purpose Feature Summary

• Supports pin assignments C, D, and E for sink configurations
• Configurable via I2C control interface
• Multiplexes AUX+/- channels to SBU pins during DisplayPort operation

Analog Switches - Special Purpose Applications

• Routing USB3.1 Gen1/Gen2 SuperSpeed signals through USB Type-C connectors
• Routing DP1.2/DP1.4 signals through USB Type-C connectors
• Sink applications such as monitors

Analog Switches - Special Purpose Procurement Notes

Verify the specific ZTFA suffix indicates the 40-contact UQFN package configuration. Confirm that the ordering information matches the required lead times and packaging quantities from the authorized distributor. Ensure compliance with RoHS and halogen-free requirements as specified in the product brief.

Analog Switches - Special Purpose Selection Notes

Select this component when designing sink-side USB Type-C interfaces requiring high-speed signal multiplexing. Ensure the design accommodates the 3.0V to 3.6V supply voltage range. Verify that the PCB layout supports the 40-contact UQFN package dimensions and thermal requirements for the intended application environment.

Analog Switches - Special Purpose Part Context

This part belongs to Diodes Incorporated's switching solutions portfolio, specifically targeting connectivity and display/video signal routing. It is part of the PI3USB31531 series, which includes variants like the ZLC package option. The device addresses the need for flexible signal path management in modern USB Type-C ecosystems.

Analog Switches - Special Purpose Replacement Considerations

The PI3USB31531ZLCX offers identical electrical performance but utilizes a TQFN package instead of the UQFN form factor. Verify mechanical fit and pin compatibility before substitution.
