Notes to
(1) The PCI-clamp diode must be enabled for 3.3-V/3.0-V LVTTL/LVCMOS.
(2) Differential HSTL and SSTL outputs use two single-ended outputs with the second output programmed as inverted. Differential HSTL and SSTL
(3) PPDS, mini-LVDS, and RSDS are only supported on output pins.
(4) LVPECL is only supported on clock inputs.
(5) Bus LVDS (BLVDS) output uses two single-ended outputs with the second output programmed as inverted. BLVDS input uses LVDS input buffer.
(6) Class I and Class II refer to output termination and do not apply to input. 1.2-V HSTL input is supported at both column and row I/O regardless of
(7) True differential LVDS, RSDS, and mini-LVDS I/O standards are supported in left and right I/O pins while emulated differential LVDS, RSDS, and

inputs treat differential inputs as two single-ended HSTL and SSTL inputs and only decode one of them. Differential HSTL and SSTL are only
supported on CLK pins.

The Cyclone III device family supports PCI and PCI-X I/O standards at 3.0-V V
The 3.0-V PCI and PCI-X I/O are fully compatible for direct interfacing with 3.3-V PCI
systems without requiring any additional components. The 3.0-V PCI and PCI-X
outputs meet the V
sufficient noise margin.
This section describes recommended termination schemes for voltage-referenced and
differential I/O standards.
The 3.3-V LVTTL, 3.0-V LVTTL and LVCMOS, 2.5-V LVTTL and LVCMOS, 1.8-V
LVTTL and LVCMOS, 1.5-V LVCMOS, 1.2-V LVCMOS, 3.0-V PCI, and PCI-X
I/O standards do not specify a recommended termination scheme per the JEDEC
standard
Voltage-referenced I/O standards require an input reference voltage (V
