Figure 22. MAX® 10 FPGA Development Board Clocks
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.
