Pinout Comparison

Table 1 lists the changes in the pin definitions of the TUSB211 and TUSB216I devices, and highlights pin configurations that may require change when using the TUSB216I to replace the TUSB211 in an existing system.

Table 1-1 TUSB211 to TUSB216I Schematic and BOM Changes
Pin TUSB211 TUSB216I Schematic and BOM Change Notes
1 D1M D1M No change required
2 D1P D1P No change required
3 TEST SDA GPIO mode: no change required
I2C mode: add a 4.7-kΩ pullup to 1.8 V or 3.3 V; connect to master SDA.
4 CD SCL/CD No change required,

GPIO Mode: Recommended to connect the pin to a test point on the PCB.

I2C mode: add a 4.7-kΩ pullup to 1.8 V or 3.3 V; connect to master SCL.
5 RSTN RSTN No change required
6 EQ

BOOST

BOM: pulldown resistor value may need to change for optimal tuning, optional.
7 D2P D2P No change required
8 D2M D2M No change required
9 ENA_HS RX_SEN/ENA_HS

No Change required. Mid RX_SEN setting is selected automatically if the pin is left disconnected.

Schematic (Optional): resistor options can be added for RX_SEN tuning.

Recommend connecting ENA_HS pin to a test point on the PCB.

10 GND GND No change required
11 VREG CDP_ENZ No change required

If CDP is not in use.

12 VCC VCC No change required
