PCB Layout of Evaluation Board
The LX7178 EVAL Board is a 4-layer board, the thickness of the board is 63mil in total. The
second layer to top layer is 7mil, the third layer to the bottom layer is 7mil.
No microvias or
blind vias are needed; each signal can leave the LX7178 directly without using any via under
the device. The layout so implemented can lower the ESL with the bypass capacitors C2, C3
and C9, only C4 is located some distance from the controller.
