(V AVDD = V DVDD = 1.7V to 1.9V, V IOVDD = 1.7V to 3.6V, R L = 100I Q1% (differential), EP connected to PCB ground, T A = -40°C to
+105°C, unless otherwise noted. Typical values are at V AVDD = V DVDD = V IOVDD = 1.8V, T A = +25°C.)

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 Q10FA.
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 PCLKOUT ) for BWS = GND. Bit time = 1/(40 x f PCLKOUT ) for BWS = 1.
