OPT3101: PCB Layout Inner Layer2

Part Number: OPT3101

Hi,

The AVSS_GND pattern cannot be found in the pcb layout inner layer2 on the evm board, so could you please tell me that reason ?

Hi Kato,

We do this on 4 layer designs with through hole PD to prevent increasing the capacitance across the PD. Layer 2 is much closer to the PD than layers 1 and TOP due to the inner core in the PCB.

Best,

Alex
