2.1.6.2. ATX PLL Usage Model When Driving GXT Channels

  • If ATX PLL IP is configured as the “Main ATX PLL” (Local ATX PLL output) the ATX PLL Master Clock Generation Block (MCGB) cannot be used.
  • If ATX PLL IP is configured as an “Adjacent ATX PLL” (selecting input from ATX PLL below/above), the MCGB in the 3-pack cannot be used.
    • In the same 3-pack as a Main ATX PLL or Adjacent ATX PLL, the fPLL can be configured to drive the x1 clock lines.
