TUSB1146中文资料Type-C USB 3.2 交替模式转接驱动器/多路复用器数据手册TI规格书

描述 Description

The TUSB1146 is a VESA USB Type-C™ Alt Mode redriving switch supporting USB 3.2 data rates up to 10 Gbps and DisplayPort 2.0 up to 10 Gbps for downstream facing port (Host). The device is used for configurations C, D, and E from the VESA DisplayPort Alt Mode on USB Type-C standard. This protocol-agnostic linear redriver is also capable of supporting other USB Type-C Alt Mode interfaces such as HDMI Alt Mode.

The TUSB1146 incorporates an innovative, adaptive receiver equalization (AEQ) feature. The AEQ feature will automatically find the best ISI compensation setting between the USB device and the TUSB1146. Because the AEQ finds the best setting, interoperability between a USB Host and USB Device is vastly improved. The TUSB1146 operates on a single 3.3-V supply and comes in a commercial temperature range and industrial temperature range.
