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: Common mode voltage is defined as V_IH.
NOTE 3: For single-ended applications, the maximum input voltage for PCLK0, nPCLK0 and PCLK1, nPCLK1
is V_CC + 0.3V.

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 + 0.3V.
