Board Reference
Board references J9 and J8 are two optional input SMAs to the high-speed positive
and negative differential receiver channel while J11 and J10 are two optional output
SMAs from the high-speed positive and negative differential transmitter channel. By
default, the GXB_RX1 channel of the FPGA is connected to the Ethernet PHY through
capacitor multiplexer C59 and C58, while the GXB_TX1 channel is connected to the
Ethernet PHY through resistor multiplexer R53 and R52. You need to perform a solder
modification on the board if you intend to use the optional transceiver SMA
connectors. You can use these SMAs to connect to external circuit boards or
daughtercards for transceiver applications.

default Ethernet PHY connection or the optional transceiver SMA connectors. The
capacitors multiplexer are 0.1-μF capacitors and the multiplexer resistors are 0-Ω
resistors.
This section describes the board's memory interface support and also their signal
names, types, and connectivity relative to the Cyclone IV GX device. The board has
the following memory interfaces:

The SSRAM device consists of a single standard synchronous SRAM, providing
18-Mb of memory with a 16-bit data bus. This device is part of the shared FSML bus
which connects to the flash memory, SRAM, and MAX II CPLD EPM2210 System
Controller.
