D26
Load LED
Illuminates during embedded USB-Blaster data transfers.
D27
Error LED
Illuminates when the FPGA configuration from flash fails.
D24
Power LED
Illuminates when 12-V power is present.
D32, D33, D34,
D35
Ethernet LEDs
Shows the connection speed as well as transmit or receive activity.
D3, D4
HSMC port A LEDs
You can configure these LEDs to indicate transmit or receive activity.
D1
HSMC port A Present LED
Illuminates when a daughtercard is plugged into the HSMC port A.
D14, D15
HSMC port B LEDs
You can configure these LEDs to indicate transmit or receive activity.
D2
HSMC port B Present LED
Illuminates when a daughtercard is plugged into the HSMC port B.
D30
SDI mute LED
Illuminates when the SDI receiver is muted.
D25

PCI Express Link LEDs
You can configure these LEDs to display the PCI Express link width
(x1, x4, x8).
Clock Circuitry
X1
125 M oscillator
125.000-MHz crystal oscillator for Gigabit Ethernet, Serial RapidIO™
(SRIO), or PCI Express.
X2
156 M oscillator
156.250-MHz crystal oscillator for 10 Gigabit Ethernet or XAUI.
X3
148 M oscillator
148.500-MHz voltage controlled crystal oscillator for SDI Video.
X6
100 M oscillator
100.000-MHz (programmable to any frequency between 20–810 MHz)
crystal oscillator for PCI Express or general use such as memories.
Multiplex with CLKIN_SMA_P based on CLK_SEL switch value.
X7
155 M oscillator
155.520-MHz crystal oscillator for SONET.
X8
50 M oscillator
50.000-MHz crystal oscillator for general purpose logic.
J15, J14
Clock input SMAs
Drives LVPECL-compatible clock inputs into the U50 clock multiplexer
buffer.
J9
Clock output SMA
Drives out 2.5-V CMOS clock outputs from the FPGA.
General User Input and Output
D6-D13
D16-D23
User LEDs
16 user LEDs. Illuminates when driven low.
SW3
User DIP switch
Octal user DIP switches. When the switch is ON, a logic 0 is selected.
S1
Reset configuration
push-button switch
Press to reconfigure the FPGA from the flash memory.
S2
CPU reset push-button switch
Press to reset the Max II CPLD EPM2210 System Controller and FPGA
logic.
S3, S4, S5
General user push-button
switches
Three user push-button switches. Driven low when pressed.
SW2
Power monitor rotary switch
Selects the power rail being measured. It also selects the FPGA image
to load on power-up; 0 selects factory image and 1 selects
user-defined image.
