1D1MD1MNo change required
2D1PD1PNo change required
3SDASDAGPIO mode: no change required
I2C mode: no change required, To enable I2C: add a 4.7 kΩ pullup to 3.3 V (or 2 kΩ pullup to 1.8 V for the TUSB216I) and connect to master SDA.
4CDSCL/CDGPIO Mode: no change required, recommend to connect pin to a test point on the PCB.
I2C mode: no change required, To enable I2C: add a 4.7 kΩ pull up to 3.3 V (or 2 kΩ pullup to 1.8 V for the TUSB216I) and connect to master SCL.
5RSTNRSTNNo change required
6EQBOOSTBOM: pull-down resistor value might need to change for optimal tuning.
7D2PD2PNo change required
8D2MD2MNo change required
9DC_BOOST/ENA_HSRX_SEN/ENA_HSBOM: populated resistor option might need to change for optimal tuning.

Recommend to connect pin to a test point on the PCB.

10GNDGNDNo change required
11VREGCDP_ENZNo change required if CDP is not in use. Add 10-K pull-down to enable CDP mode.
