2 The 1.0 V LVCMOS I/O standard is available only for the following device combinations and subject to device OPN availability:
10M02/04/08/16/25/40/50 + SC/DC/SA/DA/DD + U324/U169/M153/F256/F484/F672 + I7/C7/C8
3 Available in Intel® MAX® 10 16, 25, 40, and 50 devices only.
4 The inputs treat differential inputs as two single-ended inputs and decode only one of them.
5 The outputs use two single-ended output buffers with the second output buffer programmed as inverted.
6 You can use dedicated LVDS transmitters only on the bottom I/O banks. You can use LVDS receivers on all I/O banks.
7 The 1.8 V LVDS buffers are supported as inputs on all high-speed I/O banks but as outputs only on the bottom banks. The low-speed and high-speed DDR3 I/O banks do not support 1.8 V LVDS. The 1.8 V LVDS I/O standard is supported in industrial- and commercial-grade Intel® MAX® 10 dual supply devices except in packages V36 and V81.
8 The outputs use two single-ended output buffers with the second output buffer programmed as inverted. A single series resistor is required.
9 Requires external termination resistors.
10 The outputs uses two single-ended output buffers as emulated differential outputs. Requires external termination resistors.
