Notes (1), (2)
Symbol
Parameter
Conditions
tINHPLL
Hold time for input or bidirectional pin using column IOE
input register with global clock fed by enhanced PLL with
default phase setting
tOUTCOPLL
Clock-to-output delay output or bidirectional pin using
column IOE output register with global clock enhanced PLL
with default phase setting
CLOAD = 10 pF
Notes to Table 6–53:
(1) These timing parameters are sample-tested only.
(2) These timing parameters are for column IOE pins. Row IOE pins are 100- to 250-ps slower depending on device,
speed grade, and the specific parameter in question. You should use the Quartus II software to verify the external
timing for any pin.
Tables 6–54 through 6–59 show the external timing parameters on column
and row pins for EP1SGX10 devices.
