PTN36043BXY

Signal Buffers, Repeaters, Splitters Overview

The PTN36043BXY is a low-power, two-differential-channel, 2-to-1 active multiplexer/demultiplexer switch designed for USB Type-C applications. It integrates a first-generation SuperSpeed USB 3.1 (USB 3.0) redriver IC to extend signal reach and maintain integrity. The device supports the USB 3.1 Gen 1 specification and features optimized performance with minimal crosstalk. It includes integrated termination resistors for simultaneous source and load matching, automatic receiver termination detection, and transmit de-emphasis. The B variant specifically enables data transparency during continuous polling states by routing LFPS on one channel while keeping the other electrically idle.

Signal Buffers, Repeaters, Splitters Feature Summary

• Integrates a SuperSpeed USB 3.1 Gen 1 redriver with receive equalization and transmit de-emphasis capabilities.
• Features a 2:1 mux/demux architecture with differential signaling and integrated termination resistors.
• Supports transparent data transmission during link polling states in the B variant configuration.
• Includes advanced power management with dynamic circuit activation/deactivation for U2/U3 low-power modes.

Signal Buffers, Repeaters, Splitters Applications

• USB Type-C host and device port expansion
• Signal conditioning for high-speed serial interfaces
• Mobile computing and portable electronics

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'XY' against official NXP documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating voltage of 1.8V and control logic levels before integration into the design.

Signal Buffers, Repeaters, Splitters Selection Notes

Select the PTN36043B variant over the A variant if the application requires transparent data handling during continuous polling states. Consider the DHX2QFN18 package dimensions (2.4mm x 2.0mm) for PCB layout constraints. Verify that the system operates within the specified -40°C to +85°C temperature range.

Signal Buffers, Repeaters, Splitters Part Context

This component belongs to NXP's USB Type-C active switch portfolio, designed to complement controllers like the PTN5150A. It addresses signal degradation issues in mobile designs by providing both switching and signal regeneration functions in a compact form factor.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PTN36043A is a functional alternative but lacks the specific continuous polling transparency feature found in the B variant. Verify pinout compatibility and software control requirements when substituting between variants.
