Input and output parameters vary 1:1 with V_CC. V_EE can vary +0.925V to -0.5V.
NOTE 1: Outputs terminated with 50Ω to V_CC - 2V.
NOTE 2: Common mode voltage is defined as V_IH.
NOTE 3: For single-ended applications, the maximum input voltage for PCLKA, nPCLKA and PCLKB, nPCLKB
is V_CC + 0.3V.

NOTE 1: Measured from the differential input crossing point to the differential output crossing point.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.
Measured at the output differential cross points.
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 the differential cross points.
NOTE 4: This parameter is defined in accordance with JEDEC Standard 65.
