6.13 CC PHY Parameters

Operating under these conditions unless otherwise noted: 3.0 V ≤ V_{VIN_3V3} ≤ 3.6 V or V_{Px_} _VBUS ≥ 3.9 V

PARAMETER		TEST CONDITIONS	MIN	TYP	MAX	UNIT
Transmitter
V_TXHI	Transmit high voltage on Px_CCy	Standard External load	1.05	1.125	1.2	V
V_TXLO	Transmit low voltage on Px_CCy	Standard External load	-75		75	mV
Z_DRIVER	Transmit output impedance while driving the CC line using Px_CCy	measured at 750 kHz	33		75	Ω
t_Rise	Rise time. 10 % to 90 % amplitude points on Px_CCy, minimum is under an unloaded condition. Maximum set by TX mask	C_{Px_CCy}= 520 pF	300			ns
t_Fall	Fall time. 90 % to 10 % amplitude points on Px_CCy, minimum is under an unloaded condition. Maximum set by TX mask	C_{Px_CCy}= 520 pF	300			ns
Receiver
Z_BMCRX	receiver input impedance on Px_CCy	Does not include pull-up or pulldown resistance from cable detect. Transmitter is Hi-Z.	1			MΩ
C_CC	Receiver capacitance on Px_CCy⁽¹⁾	Capacitance looking into the CC pin when in receiver mode			120	pF
V_{RX_SNK_R}	Rising threshold on Px_CCy for receiver comparator	sink mode (rising)	499	525	551	mV
V_{RX_SRC_R}	Rising threshold on Px_CCy for receiver comparator	source mode (rising)	784	825	866	mV
V_{RX_SNK_F}	Falling threshold on Px_CCy for receiver comparator	sink mode (falling)	230	250	270	mV
V_{RX_SRC_F}	Falling threshold on Px_CCy for receiver comparator	source mode (falling)	523	550	578	mV

(1) C_CC includes only the internal capacitance on a Px_CCy pin when the pin is configured to be receiving BMC data. External capacitance is needed to meet the required minimum capacitance per the USB-PD Specifications (cReceiver). Therefore, TI recommends adding C_{Px_CCy} externally.
