Table 4–54 shows the external I/O timing parameters when using global
clock networks.
tXZPLL
Synchronous IOE output enable register to output pin disable delay
using regional clock fed by Enhanced PLL with default phase setting
tZXPLL
Synchronous IOE output enable register to output pin enable delay
using regional clock fed by Enhanced PLL with default phase setting
(1)
These timing parameters are sample-tested only.
(2)
These timing parameters are for column and row IOE pins. You should use the
Quartus II software to verify the external timing for any pin.
