Maximum set by TX mask CCCy = 520 pF 300 ns tFall Fall time. 90 % to 10 % amplitude points on CCy, minimum is under an unloaded condition. Maximum set by TX mask CCCy = 520 pF 300 ns VPHY_OVP OVP detection threshold for USB PD PHY 0 ≤ VVIN_3V3 ≤ 3.6 V, 0 ≤ VPP5V ≤ 5.5 V, VVBUS ≥ 4 V. Initially VCC1 ≤ 5.5 V and VCC2 ≤ 5.5 V, then VCCx rises 5.5 8.5 V Receiver ZBMCRX Receiver input impedance on CCy Does not include pullup or pulldown resistance from cable detect. Transmitter is Hi-Z 1 MΩ CCC Receiver capacitance on CCy (1) Capacitance looking into the CC pin when in receiver mode 120 pF VRX_SNK_R Rising threshold on CCy for receiver comparator Sink mode (rising) 499 525 551 mV VRX_SRC_R Rising threshold on CCy for receiver comparator Source mode (rising) 784 825 866 mV VRX_SNK_F Falling threshold on CCy for receiver comparator Sink mode (falling) 230 250 270 mV VRX_SRC_F Falling threshold on CCy for receiver comparator Source mode (falling) 523 550 578 mV (1) CCC includes only the internal capacitance on a 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 CCCy externally.
