[SI-LIST] 4 Layer Stackups

Greetings All,
 

Can anyone shed some light on what would be considered a "good" 4 layer
stackup?  Does anyone have suggestions for reference material I could
read?

 

These are the 2 versions we are currently considering.  Does anyone know
of any pros/cons for these stackups?

 

Sig1/PWR

GND

PWR

Sig2/GND

 

or

 

GND

Sig1/PWR

Sig2/PWR

GND

 

 

 

Finally, for a design under 15MHz what is more important: inter-plane
capacitance (pwr/gnd distance minimized) or signal/plane distance to be
minimized?

 

 

Thanks,

Nic Torchia
