Difference in Maximum VCO and Output Frequencies of CY7B9945V

Question: Why the maximum output frequency is 200MHz when the VCO frequency can go upto 800MHz in CY7B9945?



Although CY7B9945V VCO goes up to 800 MHz, there's always a divide by 4 internally (not shown in data sheet), so the maximum frequency to divide is 200 MHz. So CY7B9945V has an internal divider.
