TLIN1021A-Q1: Vias in Layout Example

Youhei Miyaoka

Part Number: TLIN1021A-Q1

Hello team,

In layout example, there is description; "Make all ground and power connections as short as possible and use at least two vias to minimize the total loop inductance.", is this two vias mandatory requirement? If yes, please tell me the reason as well.

Regards,

Youhei MIYAOKA

    Hi Youhei,

    This is typical PCB layout best practice. The more vias, the less impedance and inductance for a more stable GND.

    Hence, if it is designed intentionally and works great for the system environment, then no concerns. However, this is typical for optimal performance, thanks.

    Best Regards,

    Michael.
