LPC54608 XTAL PCB layout

実奥山 — Sun, 21 Oct 2018 14:23:31 GMT

I'm planning to make 4 layer board of LPC54608.

The thickness is t1.6.

I attach the outline of athe board.

L1 is circuit layer.

L2 is GND layer.

L3 is power layer.

L4 is circuit layer.

I'm planning to empty L2,L3 under XTAL.

But I don't know how to do L4.

Should I put GND pattern in L4?

Or should I empty L4?

Please instruct me.

Hi,

The first thing to consider it is your Stackup, L2 GND and L3 Power it is a mistake, you should use L1 Circuit, L2 Power L3 Circuit, L4 GND.

Have a great day,
Sol
