7.3 Recommended PWB layout
General PWB layout recommendations for SCA3000 products (refer to Figure 15, Figure 16 and
Figure 17):
1. Locate 100 nF SMD capacitors right next to the SCA3000 package.
2. 1 µF capacitors can be located near the node where AVDD and DVDD are routed on separate
ways.
3. Use separate ground planes for AGND and DGND. Connect separate ground planes together
on PWB.
4. Use double sided PWB, connect the bottom side plane to DGND.
