FPGA+ 2DDR2 core board is based on ALTERA

EP4CE75F23C8. This chip develops a high-performance core board with high

speed, high bandwidth and high capacity. It is suitable for video image

processing and high-speed data acquisition.

This core board uses two pieces of MICRON's MT47H64M16HR-3IT

DDR2 chip with a total capacity of 2Gbit; two DDR2s form a 32-bit bus mode,

and the read/write data bandwidth between FPGA and DDR2 is up to 8.5Gb;

this configuration can satisfy 4 channels of 1080p video processing needs.

This core board extends 168 IO ports (73 pairs of LVDS differential), which

is a good choice for users who need a lot of IO. Moreover, the FPGA chip to the

interface is treated with the same length, and the core board size is only 60*60

(mm), which is very suitable for secondary development.

Part 2: DDR2 DRAM

Figure 2-1 detailed part of the DDR2 schematic (For details, please refer to

the schematic provided by us.)

Further, in order to allow DDR2 work properly, it is necessary to provide a

reference voltage VREF and the termination voltage VTT is DDR2 DDR2 chip
