Reference Manual

SW8 PCI Express DIP switch

Controls the PCI Express lane width by connecting the

prsnt

pins

together on the PCI Express edge connector. This switch is located at

the back of the board.

S1 Program select push button

Toggles the program LEDs, which selects the program image that

loads from flash memory to the FPGAs.

Program configuration push

button

Configures the FPGAs from flash memory image based on the program

LEDs.

D1, D2, D3 Program LEDs

Illuminates to show the LED sequence that determines which flash

memory image loads to the FPGA when you press the program select

push button.

D12 Load LED Illuminates during FPGA configuration.

D13 Configuration done LED Illuminates when the FPGA is configured.

D14 Error LED Illuminates when the FPGA configuration from flash fails.

D27 Power LED Illuminates when 5-V power is present.

D4, D5 System Console TX/RX LEDs

Indicate the transmit or receive activity of the System Console USB

interface. The TX and RX LEDs would flicker if the link is in use and

active. The LEDs are either off when not in use or on when in use but

idle.

D15, D16 JTAG TX/RX LEDs

Indicate the transmit or receive activity of the JTAG chain. The TX and

RX LEDs would flicker if the link is in use and active. The LEDs are

either off when not in use or on when in use but idle.

D10, D11 HSMC TX/RX LEDs

You can configure these LEDs to indicate transmit or receive activity on

the HSMC interface.

D21 HSMC Present LED Illuminates when you plug a daughtercard into the HSMC connector.

D36 FMC Present LED Illuminates when you plug a daughtercard into the FMC connector.

D42, D43 PCI Express Gen2/Gen3 LED

You can configure these LEDs to illuminate when PCI Express is in

Gen2 or Gen3 mode.

D38, D39, D40,

D41

PCI Express Link LEDs

You can configure these LEDs to display the PCI Express link width

(x1, x4, x8, x16).

706.25 MHz, 206.25 MHz, and 206.25 MHz.

U100 Quad-output oscillator

Programmable oscillator with default frequencies of 100 MHz (LVDS),

100 MHz (LVDS), 100 MHz (1.8-V CMOS), and 100 MHz (LVDS).

X91 Quad-output oscillator

Programmable oscillator with default LVDS frequencies of 100 MHz,

644.53125 MHz, 644.53125 MHz, and 100 MHz.
