shows the external I/O timing parameters when using global
clock networks.
t
XZPLL
Synchronous IOE output enable register to output pin disable delay
using regional clock fed by Enhanced PLL with default phase setting
t
ZXPLL
Synchronous IOE output enable register to output pin enable delay
using regional clock fed by Enhanced PLL with default phase setting
Notes to
Table 4–53
:
(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.
