PLL lock times
DLL lock times
Notes:
1. DLL lock times are a function of the ratio between the output clock and the coherency system bus clock (csb_clk). A 2:1 ratio
2. The csb_clk is determined by the CLKIN and system PLL ratio. See

Output leakage current
Output high current (V
results in the minimum and an 8:1 ratio results in the maximum.
