[SI-LIST] Assymetric stip line

hi,
Assymetric stip line

Layer 1 GND
Dielectic 8mils
Layer 2 Signal (100MHz to 200MHz)
Dielectric 12mils
Layer 3 Power (Split plane 3.3V and GND)

The high speed signals (Around 50 signals) in the Layer 2 encounters split in 
the 
layer 3.  The split width is 10mils. Please let me know whether this split will 
have serious impact on the signal quality.

More over the split plane is 12 mils away from the signal layer.  But the Full 
GND
plane (Layer1) is near to the signal.  Won't the signal will take this GND 
plane as reference
for their return current.


Thanks in advance
