Texas Instruments TUSB542RWQR
The TUSB542 is a dual channel USB 3.1 Gen1
(5 Gbps), also known as USB-C, re-driver supporting systems with USB Type-C™ connectors. Thedevice offers signal conditioning plus the ability to switch the USB SS signals for the USB Type-C™flippable connector. The TUSB542 can be controlled through the SEL pin by an external ConfigurationChannel Logic Controller to properly mux the signals.
The TUSB542 incorporates receiver equalization and transmitter de-emphasis to maintainsignal integrity on both transmit and receive data paths. The receiver equalization offers multiplegain settings to overcome channel degradation from insertion loss and inter-symbol interference. Tocompensate for downstream transmission line losses, the output driver supports de-emphasisconfiguration. Additionally, automatic LFPS de-emphasis control allows for full compliance.
The TUSB542 offers low power consumption on a 1.8-V supply with its ultra-low powerarchitecture. The re-driver supports low power modes, which further reduce the idle powerconsumption.
The USB Type-C™ redriver is available in a small ultra-thin package, which is suitablefor many portable applications.
