8.2.1 Design Requirements

TUSB216-Q1 requires a valid reset signal as described in the Power Supply Recommendations section. The capacitor at RSTN pin is not required if a micro controller drives the RSTN pin according to recommendations.

For this design example, use the parameters shown in Table 8-1, Table 8-2 and Table 8-3.

Table 8-1 Design Parameters for 5-V Supply With High Loss System
PARAMETERVALUE(1)
VCC5 V ±10%
I2C support required in system (Yes/No)No
Edge and DC BoostRBOOSTBOOST LevelBoost Level 1:
RBOOST = 1.8 kΩ
0-Ω0
1.8 kΩ ±1%1
3.6 kΩ ± 1%2
Do Not Install (DNI)3
RX SensitivityRRXSEN1RRXSEN2RX_SEN LevelHigh RX Sensitivity Level:
RRXSEN1 = 37.5 kΩ
RRXSEN2 = 12.5 kΩ
22 kΩ - 40 kΩ (27 kΩ typical)Do Not Install (DNI)Low
Do Not Install (DNI)Do Not Install (DNI)Medium
37.5 kΩ(2)12.5 kΩHigh
(1) These parameters are starting values for a high loss system. Further tuning might be required based on specific host or device as well as cable length and loss profile. These settings are not specific to a 5 V supply system could be applicable to 3.3 V supply system as well.
(2) This resistor is needed for a 5 V supply to divide the voltage down so the RX_SEN pin voltage does not exceed 5.0 V.
Table 8-2 Design Parameters for 3.3-V Supply With Low to Medium Loss System

(1) These parameters are starting values for a low to medium loss system. Further tuning might be required based on specific host or device as well as cable length and loss profile. These settings are not specific to a 3.3 V supply system could be applicable to 5 V supply system as well.

(1) These parameters are starting values for a low to medium loss system. Further tuning might be required based on specific host or device as well as cable length and loss profile. These settings are not specific to a 2.3 V – 4.3 V supply system could be applicable to 5 V supply system as well.
(2) This resistor is needed for a VBAT supply (2.3 V – 4.3 V) to divide the voltage down so the RX_SEN pin voltage does not exceed 5.0 V.
