The TUSB542 is a dual channel USB 3.1 Gen1 (5Gbps), also known as USB-C, re-driver supporting systems with USB Type-C connectors. The device 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 Configuration Channel Logic Controller to properly mux the signals.

The TUSB542 incorporates receiver equalization and transmitter de-emphasis to maintain signal integrity on both transmit and receive data paths. The receiver equalization offers multiple gain settings to overcome channel degradation from insertion loss and inter-symbol interference. To compensate for downstream transmission line losses, the output driver supports de-emphasis configuration. Additionally, automatic LFPS de-emphasis control allows for full compliance.

The TUSB542 offers low power consumption on a 1.8V supply with its ultra-low power architecture. The re-driver supports low power modes, which further reduce the idle power consumption.

The USB Type-C redriver is available in a small ultra-thin package, which is an excellent choice for many portable applications.
