Cyclone II High-Speed I/O Banks
pins in each I/O bank (on both rows and columns) support the high-
speed I/O interface. Cyclone II pin tables list the pins that support the
high-speed I/O interface.

I/O Bank 4
I/O Bank 4 Also Supports
the SSTL-18 Class II,

Notes to Figure 11–1:
(1) The LVPECL I/O standard is only supported on clock input pins. This I/O standard is not supported on output
pins.
(2) The differential SSTL-18 and SSTL-2 I/O standards are only supported on clock input pins and PLL output clock
pins.
(3) The differential 1.8-V and 1.5-V HSTL I/O standards are only supported on clock input pins and PLL output clock
pins.
