Notes to Table 1–37:

(1) Hyper transport is not supported by Stratix III devices.

(2) LVPECL outputs are not supported by Stratix III devices.

(3) You can change the Quartus II timing conditions using the Advanced I/O Timing feature.

(4) V

CC is nominally 1.1 V less 50 mV (1.05 V).

(5) Terminated I/O standards require an additional 30 mV IR drop on V

CC (1.02 V).

(6) Terminated I/O standards require an additional 50 mV IR drop on V

CCIO and VCCPD.
