Notes to
(1) Differential voltage-referenced standards can only be used for clocking. These I/O standards are only supported on the GCLK and PLL_OUT
(2) Side I/O banks support dedicated differential buffers. Top and bottom I/O banks support differential signaling with an additional resistor network

Flexible I/O Banks
Simultaneous support of various I/O standards is possible with efficient I/O
groupings in banks. Each bank must be supplied with one V

Cyclone III Device I/O Features
Each Cyclone III I/O bank has a VREF bus to accommodate voltage-referenced I/O
standards. Multiple VREF pins within an I/O bank feed the common VREF bus. Each
