3 Description
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. 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
1.8-V 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 suitable for many portable
applications.
