FUSB340TMX-HXY

The FUSB340TMX is a high-speed bidirectional passive switch in a multiplexer or demultiplexer configuration, designed for USB Type-C applications supporting USB 3.1 Gen 1 and Gen 2 data rates. Based on the control pin SEL, the device switches differential channels between port L0 or port L1 and port C0. The FUSB340TMX is a general-purpose analog differential passive switch suitable for any high-speed interface application requiring a common-mode voltage range of 0 to 2V and differential signal amplitudes up to 1.8Vₚ₋ₚ. It employs adaptive tracking technology to ensure consistent channel performance across the entire common-mode voltage range. The device's excellent dynamic characteristics enable high-speed switching with minimal signal eye diagram degradation and very low added jitter. Operating power consumption is less than 2mW, with a shutdown mode accessible via the EN pin that reduces power consumption to less than 20μW. The FUSB340TMX is available in a QFN 2x3 (X2-QFN-18) package that is lead-free and halogen-free, making it ideal for mobile and space-constrained applications.
