50.000 MHz 2.5 V CMOS M9 MAX 10 clock
U2

CLK_DDR3_100_N

100.000 MHz Differential SSTL-15 N15 DDR3 clocks
U2

CLK_DDR3_100_P

100.000 MHz Differential SSTL-15 N14 DDR3 clocks
U2

CLK_LVDS_125_N

125.000 MHz 2.5 V LVDS R11 LVDS clocks
U2

CLK_LVDS_125_P

125.000 MHz 2.5 V LVDS P11 LVDS clocks
Note: For signal CLK_50_MAXII, the output side voltage is 2.5V and the input side voltage is 3.3V. However, they are compatible electrically.
Note: For signals CLK_DDR3_100_P and CLK_DDR3_100_N, at the MAX 10 input side, Differential SSTL-15 is used as I/O standard because this bank's VCCIO is 1.5V.
