12 layer pcb stack up

Hi everyone,
What is best stack up for a 12 layer PCB.
Does the following hold good
Type Layer
SIGNAL - Layer 1(Top)
GROUND - Layer 2
SIGNAL - Layer 3
SIGNAL - Layer 4
GROUND - Layer 5
POWER - Layer 6
POWER - Layer 7
GROUND - Layer 8
SIGNAL - Layer 9
SIGNAL - Layer 10
GROUND - Layer 11
SIGNAL - Layer 12 (Bottom)

For fast circuits, it may be preferable to have power or ground planes separate single signal layers with controlled impedances.

Hi, I think it:

SIGNAL - Layer 1(Top)
GND - Layer 2
POWER - Layer 3
SIGNAL - Layer 4
SIGNAL - Layer 5
GND - Layer 6
POWER - Layer 7
SIGNAL - Layer 8
SIGNAL - Layer 9
GND- Layer 10
POWER - Layer 11
SIGNAL - Layer 12 (Bottom)

Nowadays, you should have power planes very near to have a low ESR capacitor for higher frecuencies (important for Power Distribution Network in high-speed design).

Good Luck!
