Notes to Tables 6–91 & 6–92:  
(1) See “Maximum Input & Output Clock Rates” on page 6–54.  
(2) When using the SERDES, high-speed differential I/O mode supports a maximum output frequency of 210 MHz  
to the global or regional clocks (that is, the maximum data rate 840 Mbps divided by the smallest SERDES J factor  
of 4).  
(3) This parameter is for high-speed differential I/O mode only.  
(4) These counters have a maximum of 32 if programmed for 50/50 duty cycle. Otherwise, they have a maximum  
of 16.  
(5) High-speed differential I/O mode supports W = 1 to 16 and J = 4, 7, 8, or 10.  
Table 6–93 reports the jitter for the DLL in the DQS phase-shift reference  
circuit.
