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 V
TH
and V
TL
.
Note 2: Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are production
tested at T
A
= +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 ±10µA.
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
TH
, V
TL
, and AC parameters are guaranteed by design and characterization, and are not production tested. Limits are set
at ±6 sigma.
Note 7: C
L
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_.
