Note:
4. These inputs are normally wired to VCC, GND, or left unconnected (actual threshold voltages vary as a percentage of VCC). Internal termination resistors hold
the unconnected inputs at VCC/2. If these inputs are switched, the function and timing of the outputs may glitch and the PLL may require an additional tLOCK
time before all data sheet limits are achieved.
5. ICCI measurement is performed with Bank1 and FB Bank configured to run at maximum frequency (fNOM = 200 MHz) and the other output bank to run at half
the maximum frequency. FS is asserted to the HIGH state.
6. This is dependent upon frequency and number of outputs of a bank being loaded. The value indicates maximum ICCN at maximum frequency and maximum
load of 25 pF terminated to 50Ω at VCC/2.
