Note 1: Current into a pin is defined as positive. Current out of a pin is defined as negative. All voltages are referenced to ground,
except VTH and VTL.
Note 2: Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are production
tested at TA = +25°C.
Note 3: To provide a mid level, leave the input open, or, if driven, put driver in high impedance. High-impedance leakage current
must be less than ±10A.
Note 4: RxCLKOUT limits are scaled based on RxOUT_ measurements, design, and characterization data.
Note 5: One output shorted at a time. Current out of the pin.
Note 6: VTH, VTL, and AC parameters are guaranteed by design and characterization, and are not production tested. Limits are set
at ±6 sigma.
Note 7: CL includes probe and test jig capacitance.
Note 8: RCIP is the period of RxCLKIN_. RCOP is the period of RxCLKOUT.
Note 9: RSKM is measured with less than 150ps cycle-to-cycle jitter on RxCLKIN_.
AC ELECTRICAL CHARACTERISTICS (continued)
(VCC = LVDSVCC = PLLVCC = +3.0V to +3.6V, VCCO = +3.0V to +3.6V, CL = 8pF, PWRDWN = high; SSG = high, open, or low;
DCB = high or low, differential input voltage |VID| = 0.1V to 1.2V, input common-mode voltage VCM = |VID / 2| to 2.4V - |VID / 2|, unless
otherwise noted. Typical values are at VCC = VCCO = LVDSVCC = PLLVCC = +3.3V, |VID| = 0.2V, VCM = +1.25V, TA = +25°C.) (Notes 6, 7, 8)
