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_CCO - 2V.
NOTE 2: Single-ended input operation is limited. V_CC ≥ 3V in LVPECL mode.
NOTE 3: Common mode voltage is defined as V_IH.
NOTE 4: For single-ended applications, the maximum input voltage for PCLK0, nPCLK0 and PCLK1, nPCLK1 is V_CC + 0.3V.

All parameters are measured ≤ 1GHz unless otherwise noted.
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.
