Description
Illuminates when the MAX II CPLD EPM2210 System Controller is
actively configuring the FPGA.
Illuminates when the FPGA configuration from flash memory fails.
Shows the connection speed as well as transmit or receive activity.
Illuminates when 9-V – 16-V DC power is present.
Sets the configuration mode to either passive serial (flash) or active
serial (EPCS). This switch is located at the bottom of the board.
Press to reset the FPGA logic.
Press to reset the MAX II CPLD EPM2210 System Controller.
Toggles the PGM LEDs which selects the program image that loads
from flash memory to the FPGA.
Configure the FGPA from flash memory based on the PGM LEDs
setting.
125-MHz crystal oscillator for PCI Express or general use such as
memories. Multiplexed with CLKIN_SMA_P/N signals based on
CLK_SEL switch value.
50-MHz crystal oscillator for configuration purpose. This oscillator is
located at the bottom of the board.
Drive LVPECL-compatible clock inputs into the clock multiplexer
buffer (U6).
Four user LEDs. Illuminates when driven low.
Two user push-button switches. Driven low when pressed.
Connector which interfaces to the provided 16 character × 2 line LCD
module.
Standard synchronous RAM which provides a 2-MB SSRAM port.
Synchronous burst mode flash device which provides a 16-MB
non-volatile memory port.
Provides 10/100/1000 BASE-T Ethernet connection via a Marvell
88E1111 PHY and the FPGA-based Altera Triple Speed Ethernet
MegaCore function in SGMII mode.
A Marvell 88E1111 PHY device for 10/100/1000 BASE-T Ethernet
connection. The device is an auto-negotiating Ethernet PHY with an
SGMII interface to the FPGA.
Interfaces to a PCI Express root port such as an appropriate PC
motherboard. Made of gold-plated edge fingers for up to ×1 signaling
in Gen1 mode.
