Source Schematic Signal Name Frequency (MHz) I/O Standard MAX® 10 FPGA Pin Number Application
X1 CLK_10_ADC 10.000 2.5 V CMOS N5 Programmable default 10 MHz clock for ADC
U2 CLK_25_ENET 25.000 2.5 V CMOS Ethernet clock
U2 CLK_25_MAX10 25.000 2.5 V CMOS M8 MAX® 10 clock
U2 CLK_50_MAXII 25.000 2.5 V/3.3V CMOS Clock for On-Board Intel® FPGA Download Cable II
U2 CLK_50_MAX10 50.000 2.5 V CMOS M9 MAX® 10 clock
U2 CLK_DDR3_100_N 100.000 Differential SSTL-15 N15 DDR3 clocks
U2 CLK_DDR3_100_P 100.000 Differential SSTL-15 N14 DDR3 clocks
U2 CLK_LVDS_125_N 125.000 2.5 V LVDS R11 LVDS clocks
U2 CLK_LVDS_125_P 125.000 2.5 V LVDS P11 LVDS clocks
Note: For signal CLK_50_MAXII, the output side voltage is 2.5 V and the input side voltage is 3.3 V. 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 1.5 V.
