6.13 CC PHY Parameters

Operating under these conditions unless otherwise noted: 3.0 V ≤ VVIN_3V3 ≤ 3.6 V or VPx_ VBUS ≥ 3.9 V
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
Transmitter
VTXHI Transmit high voltage on Px_CCy Standard External load 1.05 1.125 1.2 V
VTXLO Transmit low voltage on Px_CCy Standard External load -75 75 mV
ZDRIVER Transmit output impedance while driving the CC line using Px_CCy measured at 750 kHz 33 75 Ω
tRise Rise time. 10 % to 90 % amplitude points on Px_CCy, minimum is under an unloaded condition. Maximum set by TX mask CPx_CCy= 520 pF 300 ns
tFall Fall time. 90 % to 10 % amplitude points on Px_CCy, minimum is under an unloaded condition. Maximum set by TX mask CPx_CCy= 520 pF 300 ns
Receiver
ZBMCRX receiver input impedance on Px_CCy Does not include pull-up or pulldown resistance from cable detect. Transmitter is Hi-Z. 1 MΩ
CCC Receiver capacitance on Px_CCy(1) Capacitance looking into the CC pin when in receiver mode 120 pF
VRX_SNK_R Rising threshold on Px_CCy for receiver comparator sink mode (rising) 499 525 551 mV
VRX_SRC_R Rising threshold on Px_CCy for receiver comparator source mode (rising) 784 825 866 mV
VRX_SNK_F Falling threshold on Px_CCy for receiver comparator sink mode (falling) 230 250 270 mV
VRX_SRC_F Falling threshold on Px_CCy for receiver comparator source mode (falling) 523 550 578 mV
(1) CCC 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 CPx_CCy externally.
