KM864741 Datasheet Brief

Fully Bi-directional USB4 Re-Timer with multi-protocol support

for PC and Peripheral Applications

KM864741 is multi-protocol bidirectional Re-Timer for USB Type-CⓇ connector, which can transmit and

receive up to 40 Gb/s. It can support the USB4Ⓡ, Thunderbolt^TM3 compatibility, USB 3.2, DisplayPort^TM2.1,

and DisplayPort^TMAlt Mode, so can be used as a PC Re-Timer solution that supports USB4 backward

compatibility and peripheral standards. The receiving end is equipped with an adaptive equalizer that can

compensate for signal loss up to 35 dB, and the transmitting end is equipped with an emphasis circuit that

can compensate for up to 15 dB. This relaxes the restrictions on the placement of USB Type-C connectors

and CPU, therefore, allows customers to flexibly design mother boards and provides good interoperability.
