Notes to
(1) When J = 4 to 10, the SERDES block is used.
(2) When J = 1 or 2, the SERDES block is bypassed.
(3) The input clock frequency and the W factor must satisfy the following fast PLL VCO specification: 150  input clock frequency × W  1,040.
(4) The minimum specification is dependent on the clock source (fast PLL, enhanced PLL, clock pin, and so on) and the clock routing resource
(global, regional, or local) used. The I/O differential buffer and input register do not have a minimum toggle rate.
