AC Electrical Characteristics
Table 5A. AC Characteristics, VDD = VDDA = VDDB = VDDC = 3.3V ± 5%, TA = -40°C to 85°C
NOTE 1: Measured from the differential input crossing point to VDDX/2 of the output.
NOTE 2: Defined as skew within a bank of outputs at the same supply voltages and with equal load conditions.
NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at VDDX/2.
NOTE 4: Defined as skew across banks of outputs operating at different frequencies with the same supply voltage and equal load
conditions.
NOTE 5: Defined as skew between outputs on different devices operating at the same supply voltage and with equal load conditions.
Using the same type of inputs on each device, the outputs are measured at VDDX/2.
NOTE 6: These parameters are guaranteed by characterization. Not tested in production.
NOTE 7: This parameter is defined in accordance with JEDEC Standard 65.
Table 5B. AC Characteristics, VDD = 3.3V ± 5%, VDDA = VDDB = VDDC = 2.5V ± 5%, TA = -40°C to 85°C
For NOTES, please see Table 5A above.
