Simplified Schematic
3 Description
The TUSB542 is a dual channel USB 3.1 Gen1 (5
Gbps) 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 Type-C USB redriver is available in a small ultra-
thin package, which is suitable for many portable
applications.
