TUSB214-Q1: How is to unused DC boost?

Part Number: TUSB214-Q1

Hi team.

My customers do not want to use the DC Boost function of TUSB214-Q1.

MCU is not used, so it can not be controlled by I2C.

Can I control DC Boost with H/W only?

Or can you recommend Redriver with CDP function available and no DC boost function?

    Charles,

    TUSB214-Q1 only has a DC Boost Low setting, this is achieved by driving the DC_BOOST(2)/ ENA_HS  = L (pin is pulled low) – 40 mV. Unfortunately we do not have any other USB 2.0 redriver with CDP function and no DC boost function.
