DIP封装的全速USB是否有时钟速度限制

嗨，我想知道是否有任何时钟速度限制时，使用PIC的一个更大的包。我知道使用全速USB，你需要在48 MHz的时钟部分。如果你看蘸包，3V3USB引脚是从最近的地面0.3’。这会不会引起大量的电压纹波问题，考虑到电源和接地引脚之间的距离，部分电感会看到什么？

    Hi,

I was wondering if there is any clock speed limits on when using PIC's in a larger packages. I know to use full speed u***, you need to clock the part at 48MHz. If you look dip package the 3v3u*** pin is 0.3'' from the nearest ground. Wouldn't this cause a lot of voltage ripple problems, given the inherent inductance the part would see given the distance between the power and ground pins?
