UCC3895: UCC3895 Ground Plane

Part Number: UCC3895
Other Parts Discussed in Thread: UCC2895


I read the SLUA501 application note "UCC2895 Layout and Grounding Recommendations". Can I put the "quite ground plane" and "power grpund plane" in the same PCB layer or I have to put them in the different layers?  About the connection between GND and PGND, can I use a single trace to connect the IC GND pin and PGND pins or I have to connect them through the ground planes?
