3 Description

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.
