Texas Instruments TUSB2E22 USB 2.0-eUSB2 Dual Repeater
Texas Instruments TUSB2E22 USB 2.0-eUSB2 Dual Repeater enables the implementation of a USB 2.0 compliance port on newer processors using lower voltage processes. The TUSB2E22 is a USB-compliant eUSB2-USB 2.0 repeater supporting both the device and host modes. TUSB2E22 supports USB low-speed (LS), full-speed (FS), and high-speed (HS) signals. The device is designed to interface with eUSB2, eDSPr, or eUSPr, operating at 1.2V single-ended signaling. The Texas Instruments TUSB2E22 has four levels of compensation settings via EQ0 and EQ1 pins. These settings could be used to optimize compensation for different eUSB2 channel loss profiles.
