客户设计参考demo板,内核电压VCC的大滤波电容太多,客户板上会放4颗FPGA,470UF电解电容会占据很大位置,是否可以去掉?(或者电容个数保留,总容值保留一样,例如0.1UF的电容做成1UF,减少470UF的数量)有什么标准吗?根据PDN文件,没有找到FPGA对应的封装型号!

客户采用的1SM21 UF55这个型号,在PDN中没有找到,参考的demo板是1SM21 UF43的设计

Hi ,

I verified the pdn , the opn is not mentioned on that , from the description what I understood is that you need to remove 470UF, May I know how you have arrived the value , if the 470uf capacitor value is working fine why you needed to remove.

 

From my understanding if it is taking more space , can it be changed by a capacitor bank
