All clocks in the PNX15xx Series clock system are generated from 5 possible
sources:
•
•
•
•
•
2 identical PLLs within the CAB block
1 separate PLL for the memory system called PLL2
high frequency dividers from the 1.728 GHz PLL in the CAB
the DDS blocks within the CAB
external clock inputs, or derived from input data streams
