All parameters measured at fMAX unless noted otherwise.
NOTE 1: Measured from VDD/2 of the input to VDDO/2 of the output.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.
Measured at VDDO/2.
NOTE 3: Defined as skew between outputs on different devices operating at the same supply voltages and with
equal load conditions. Using the same type of inputs on each device, the outputs are measured at VDDO/2.
NOTE 4: These parameters are guaranteed by characterization. Not tested in production.
NOTE 5: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 6: Setup and Hold times are relative to the rising edge of the input clock.
