Figure 20. MAX 10 FPGA Development Board Clocks
Source | Schematic Signal Name | Frequency | I/O Standard | MAX 10 FPGA Pin Number | Application |
---|---|---|---|---|---|
X1 | CLK_10_ADC |
10.000 MHz | 2.5 V CMOS | N5 | Programmable default 10MHz clock for ADC |
U2 | CLK_25_ENET |
25.000 MHz | 2.5 V CMOS | - | Ethernet clock |
U2 | CLK_25_MAX10 | 25.000 MHz | 2.5 V CMOS | M8 | MAX 10 clock |
U2 | CLK_50_MAXII | 25.000 MHz | 2.5 V/3.3V CMOS | - | Clock for On-Board USB Blaster II |
U2 | CLK_50_MAX10 |
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.
