TUSB1104RNQR

Overview

The TUSB1104RNQR is a 10Gbps USB 3.2 x2 adaptive linear redriver designed for USB Type-C applications, enabling up to 20Gbps total data throughput. It operates from a single 3.3V supply and supports USB 3.2 Gen2 (10Gbps) and Gen1 (5Gbps), including low power states Disconnect, U1, U2, and U3. The device incorporates adaptive receiver equalization (AEQ) to automatically determine optimal ISI compensation settings between the redriver and connected USB devices. It features 16 EQ settings providing up to 12dB gain at 5GHz and allows configuration via I2C or pin-strap methods with selectable 1.8V or 3.3V I2C levels. The component is housed in a 40-pin WQFN package measuring 6mm by 4mm.
