This document describes the DQ groups in different modes, including x8/x9 mode, x16/x18 mode, and x32/x36 mode. It also introduces the DQ groups for DQS mode and non-DQS mode, and provides some specific DQ group configurations.
This document provides detailed pin configuration data for the Stratix II GX EP2SGX90 Field-Programmable Gate Array (FPGA). It lists specific pins, their names, primary functions, and alternative optional functions available under different operating modes.
The datasheet covers various configurations including F1508, F1152, X8/XG9, X16AX18, X32/X36, and X5 modes. It details the electrical connections for power supplies (such as VCCD_PLL7), ground references (GNDA_PLL7), and differential I/O pairs used for high-speed serial communication.
In X8/xg9 mode, this pin serves as a differential input for DIFFID_TX58p.
In x32/X36 mode, this pin serves as a differential input for DIFFID_RX49p.
