Table 4–115. High-Speed I/O Specifications
When J = 4 to 10, the SERDES block is used.
When J = 1 or 2, the SERDES block is bypassed.
The input clock frequency and the W factor must satisfy the following fast PLL VCO specification: 150 ≤input clock
frequency × W ≤1,040.
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) utilized. The I/O differential buffer and input register do not
have a minimum toggle rate.
