Spread-Spectrum Modulation
Frequency
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,
Note 2: Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are production
Note 3: To provide a mid level, leave the input open, or, if driven, put driver in high impedance. High-impedance leakage current
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: V
Note 7: C
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_.
