关于Arria 10 QDR IV的疑问

请教下~ Arria 10如果接QDR IV，最大位宽可以是多少？也就是最大可以接多少pcs(QDR颗粒36bit)，接法是跟DDR3/4一样嘛? 另外~datasheet内说，可以支持到1066Mhz，这个是指的-1的器件 还是所有器件都可以支持到？

Dear AMa,

Thank you for joining this Intel Community.

You may refer to EMIF spec estimator tools in link provided below . This tool allows you to find and compare the performance of the supported external memory interfaces in Intel® FPGAs. You’ll be able to filter down to specific features based on your targeted specifications . It also will show you what is the data width and speed grade supported based on the criteria you have chosen for analysis.
