8.2.1 Design Requirements

TUSB216 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

PARAMETER				VALUE⁽¹⁾
V_CC				5 V ±10%
I²C support required in system (Yes/No)				No
Edge and DC Boost		R_BOOST	BOOST Level	Boost Level 1: R_BOOST = 1.8 kΩ
		0-Ω	0
		1.8 kΩ ±1%	1
		3.6 kΩ ± 1%	2
		Do Not Install (DNI)	3
RX Sensitivity	R_RXSEN1	R_RXSEN2	RX_SEN Level	High RX Sensitivity Level: R_RXSEN1 = 37.5 kΩ R_RXSEN2 = 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 kΩ	High

(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

PARAMETER				VALUE⁽¹⁾
V_CC				3.3 V ±10%
I²C support required in system (Yes/No)				No
Edge and DC Boost		R_BOOST	BOOST Level	Boost Level 0: R_BOOST = 0-Ω
		0-Ω	0
		1.8 kΩ ±1%	1
		3.6 kΩ ±1%	2
		Do Not Install (DNI)	3
RX Sensitivity	R_RXSEN1	R_RXSEN2	RX_SEN Level	Medium RX Sensitivity Level: R_RXSEN1 = DNI R_RXSEN2 = DNI
	22 kΩ – 40 kΩ (27 kΩ typical)	Do Not Install (DNI)	Low
	Do Not Install (DNI)	Do Not Install (DNI)	Medium
	Do Not Install (DNI)	22 kΩ – 40 kΩ (27 kΩ typical)	High

(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.

Table 8-3 Design Parameters for 2.3-V to 4.3-V VBAT Supply With Low to Medium Loss System

PARAMETER				VALUE⁽¹⁾
V_CC				2.3 V to 4.3V
I²C support required in system (Yes/No)				No
Edge and DC Boost		R_BOOST	BOOST Level	Boost Level 0: R_BOOST = 0-Ω
		0-Ω	0
		1.8 kΩ ±1%	1
		3.6 kΩ ±1%	2
		Do Not Install (DNI)	3
RX Sensitivity	R_RXSEN1	R_RXSEN2	RX_SEN Level	Medium RX Sensitivity Level: R_RXSEN1 = DNI R_RXSEN2 = DNI
	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 kΩ	High

(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.
