(1) The input and output PLLs are calibrated at the ambient start up temperature (Ts) when the device is powered on or when reset using the PDB pin. The PLLs will stay locked up to the specified ending temperature.
(2) Supply noise testing was done without any capacitors or ferrite beads connected. A sinusoidal signal is AC-coupled to the VDD11 supply of the serializer until the deserializer loses lock.
