ONFUSB340TMX
Overview
The FUSB340TMX is a high-performance 2:1 or 1:2 differential data switch designed for USB 3.1 SuperSpeed applications. It provides a 10 Gbps bandwidth, allowing it to pass high-speed signals with minimum edge distortion while maintaining extremely low power consumption of 12uA typical. The device supports a wide supply voltage range from 1.5V to 5V, making it highly versatile for mobile and battery-powered systems.
Why Choose This Part
This switch offers an exceptional 10 GHz bandwidth, ensuring compatibility with USB 3.1 Gen 2 and PCIe Gen 3 signal integrity requirements. Its ultra-small 2mm x 2.8mm TMLP package and low 1uA shutdown current are ideal for space-constrained, power-sensitive portable electronics. Additionally, the 2 kV HBM ESD protection provides essential robustness for external-facing data ports.
Applications
Key Specifications
Getting Started
When designing with the FUSB340TMX, ensure that high-speed differential traces are length-matched and use controlled impedance to maintain signal integrity at 10 Gbps. The SEL pin controls the data path, and the OE pin can be pulled high to enter a low-power shutdown mode. Evaluation can be performed using custom breakout boards or by integrating the component into a prototype PCB following the layout guidelines for SuperSpeed differential pairs.
