Operating Conditions
Recommended Operating Conditions
This section lists the functional operation limits for AC and DC parameters for
Cyclone IV devices. Table 1–3 and Table 1–4 list the steady-state voltage and current
values expected from Cyclone IV E and Cyclone IV GX devices. All supplies must be
strictly monotonic without plateaus.
