All parameters measured at 166MHz 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 V /2.
DDO
NOTE 4: This parameter is defined in accordance with JEDEC Standard 65.
