Analog filtering on LPC2114 - Karl Olsen - Apr 16 3:59:00 2004

Hi all

The LPC2114 datasheet explains that the VSSA and VSSA_PLL pins should
nominally be the same voltage as VSS, but should be isolated to
minimize noise and error, and likewise with V18A and V3A.

Any examples of how such filtering is done?

Since the LPC2104 doesn't have a VSSA_PLL pin, the PLL should be able
to run without filtering?
