AC ELECTRICAL CHARACTERISTICS (continued)
(V_DVDD = V_AVDD = 1.7V to 1.9V, V_IOVDD = 1.7V to 3.6V, R_L = 100I Q1% (differential), EP connected to PCB ground (GND),
T_A = -40NC to +105NC, unless otherwise noted. Typical values are at V_DVDD = V_AVDD = V_IOVDD = 1.8V, T_A = +25NC)

Note 2: To provide a midlevel, leave the input open, or, if driven, put driver in high impedance. High-impedance leakage current
must be less than Q10µA.
Note 3: I_IN min due to voltage drop across the internal pullup resistor.
Note 4: Specified pin to ground.
Note 5: Specified pin to all supply/ground.
Note 6: Guaranteed by design and not production tested.
Note 7: Measured in serial link bit times. Bit time = 1/(30 x f_PCLKIN) for BWS = 0. Bit time = 1/(40 x f_PCLKIN) for BWS = 1.
