TUSB2E22: RESEB pin needed pull-up?

Part Number: TUSB2E22

Hello Guys,

Good day.

For RESETB pin(E4) of TUSB2E22 eUSB2-USB 2.0 Dual Repeater, do we need pull-up resistor? 

Datasheet shows this is not an option but the schematic for the TUSB2E22EVM-CAT shows the RESETB pulled up to 1.8V_IO.

Thanks and regards,

Art

    Hi Art,

    The RC circuit is not required, it was just added since we put a push button for reset on the board.

    Please make sure the reset timing in the system meets the requirements in Section 7.7 of the datasheet.
