Table 2–12. Cyclone I/O Standards
There is no megafunction support for EP1C3 devices for the PCI compiler. However, EP1C3 devices support PCI
by using the LVTTL 16-mA I/O standard and drive strength assignments in the Quartus II software. The device
requires an external diode for PCI compliance.
EP1C3 devices in the 100-pin TQFP package do not support the LVDS and RSDS I/O standards.
This I/O standard is only available on output clock pins (PLL_OUT pins). EP1C3 devices in the 100-pin package
do not support this I/O standard as it does not have PLL_OUT pins.
