Texas Instruments TUSB521-Q1 USB Type-C™ 5Gbps Linear Redriver
Texas Instruments TUSB521-Q1 USB Type-C™ 5Gbps Linear Redriver has 1:2 DeMUX or 2:1 MUX functions for USB Type-C applications. The TUSB521-Q1 is intended to reside between a Host and a USB-C receptacle or between a USB device and a USB-C receptacle. The TUSB521-Q1 supports USB 3.2 data rates up to 5Gbps and supports USB 3.2 low power states (Disconnect, U1, U2, and U3)
The Texas Instruments TUSB521-Q1 provides sixteen levels of receive linear equalization to compensate for inter-symbol interference (ISI) due to board and cable trace loss. The device operates on a single 3.3V supply and has an automotive grade 2 temperature range.
